"Do you really think that wave and particle can exist at the same time?" "That's nonsense. How can something be continuous and dispersed at the same time?"
"This came from the mouth of Magic Star Speaker Lin En. If he wasn't absolutely sure, who would destroy his reputation in front of thousands of people?" Raphael interrupted the argument. He had great confidence in the research of this Magic Star.
"So what even if it's a magic star? Doesn't it mean there's no way to make mistakes if it's so famous?" A great wizard from the empire sneered and said that as long as one is a human being, there will be mistakes.
It has only been a little over a year since optics was established, and no one dares to say that they can fully understand it.
Compared to the debates among ordinary wizards, Anthony looked at the disclaimer in his hand for a long time without saying a word.
The above content is very brief, which means that those who sign the agreement are willing to bear all the consequences of listening to quantum theory, but... the meaning behind it is chilling.
"Teacher, should we sign or not?" Fulla asked hesitantly, with a worried look on her face.
She did not have the same firm belief as Anthony, so she had long lost the ability to sense electric charge. She was well aware of the [Spellcasting Obstacles] and could not help but feel a little bit of retreat in her heart.
"Sign, of course I have to sign!" Anthony said without hesitation.
He believed that his research was absolutely correct, light is a wave, and it is an electromagnetic wave!
A magical glow appeared on Anthony's fingertips, which marked Mo's signature on the disclaimer. He then handed it to Fulla and asked her to give it to Lynn.
"Yes, teacher!" Seeing that Anthony had made up his mind, Fulla said no more. She signed her own disclaimer and then returned to the exhibition hall with the two statements.
After Fulla left, Anthony closed his eyes. After about two or three seconds, he suddenly breathed a sigh of relief and looked much more relaxed... He was still able to use lightning magic, which was good, very good!
On the other hand, Fulla, who came to ask for an audience with Speaker Lin, was rejected because there were too many people who wanted to find this magic star.
Raphael and others who had connections came here to discuss the photoelectric theory. There were also some wizards who prepared generous gifts to build relationships with the new speaker. Add to that those who came to submit disclaimers, and it was a mess! Lin En, who was worrying about how to launch a single particle, certainly would not spend his time and energy here at this time. He closed the door in the name of making experimental equipment.
Even the requests from several speakers were no exception - Lynn simply gave them a few research manuscripts and sent them away.
Microeconomics and macroeconomics are completely two sets of theories. Explaining them one by one is not only time-consuming and laborious, but the other party may not be able to understand them. It is better to wait until tomorrow's academic seminar to explain them together, so as to avoid having to repeat the explanations several times.
Johnny and Alok were standing guard at the door, apologetically informing everyone who wanted to meet that Speaker Lynn was preparing for tomorrow's seminar, and accepted the disclaimers they brought.
The efforts of the two also gave Lin En, who was in the room, some free time, and he began to think about how to emit particles.
Initially, his goal was to use alchemy to replicate the Federation's particle extractor, but after spending half a month on it, he discovered that the device was too difficult to create. Even though he could now achieve atomic-level control, he still couldn't do it.
But it makes sense when you think about it. In addition to using a strong magnetic field, this thing also uses quantum technology...
So Lin En could only consider some relatively old methods - such as thermal field emission electron gun!
…
The night passed in a flash.
But this night was not peaceful and not many people could sleep well.
Fortunately, as a wizard, staying up late is nothing. Sometimes it is normal to work hard for several days to concentrate on studying a spell. Almost every other morning, the exhibition hall was full of people.
Anthony had also arrived and glanced across the rows of seats in the large exhibition hall. Only about 30% of the seats were empty. It seemed that not many people were scared off by the disclaimer.
But it is true, the debate about the nature of light will be decided today, and any wizard who still has the desire to learn will never let go of this opportunity.
Anthony was very disdainful of those who retreated. They had lost the faith to pursue the truth and their path in magic studies might have come to an end!
At about eight o'clock in the morning, several speakers had arrived, including Lin En, who also asked Alok and others to carry out his experimental device.
"Isn't that my double-slit interference experiment?" Jeffrey said in surprise.
Anthony and others also recognized it, after all, the two were so similar.
They all have the launching device on the left, the partition in the middle, and the photosensitive screen on the right.
Under everyone's discussion, Lin En also nodded. "Yes, this is the double-slit interference experiment. To be precise, I have modified it to some extent!"
"The device on the left is what I call a thermal field emission electron gun. It consists of five parts: filament, cathode, grid, anode, and deflection coil..."
With a wave of his hand, Lin En cut the outer shell apart with incredible precision without damaging the internal structure at all. He then explained to everyone its operating principle.
The so-called filament is not the hair of a fire lion, but a tungsten filament. When powered on, it converts electrical energy into heat energy and heats the cathode, thereby releasing and emitting a large number of electrons.
These electrons will be blocked by the grid, and by adjusting its relative position with the cathode, the amount of electron beam passing through can be controlled. Finally, they are accelerated under the electric field generated by the anode, and their position is adjusted by the deflection coil, and finally the electrons are emitted one by one.
Lynn's explanation was very professional. Many of the terms confused the wizards present. Fortunately, they all understood the last part. This magic star found a way to emit single electrons and was ready to use it to conduct experiments.
"But... shouldn't it be photons?" a young witch muttered softly.
The sound was very soft, but all the wizards present heard it clearly and saw it with great sensitivity.
Lin En rolled his eyes. Emitting a single photon is more troublesome than emitting an electron.
"It's okay, it's all the same!" Lin En said with a smile. As microscopic particles, they all have quantum phenomena.
After Lin En explained, he stopped talking and looked at everyone and spoke again. "My experiment is very simple. I use an electron gun to shoot electrons into the double slits one by one, and then observe their distribution through the special fluorescent screen at the back..."
"What do you think will happen if particles pass through the double slits one by one?" Lin En suddenly asked.
"Then let's give it a try!" Lynn did not agree or reject Glenn's words. He directly activated the thermal field emission electron gun. Under everyone's attention, the tungsten filament lit up due to the heat...
In the invisible microscopic realm, one accelerated electron after another crashes forward at an extremely fast speed.
Since the holes are very small, it is not easy for the electrons to pass through, so most of them hit the partition.
After waiting for about five seconds, Harov said solemnly, "It's over!"
Arad and others opened their eyes wide, staring at the photosensitive screen behind the partition, and then they realized that a tiny dot had suddenly lit up on it.
This means that Lynn's thermal field emission electron gun successfully hit a single electron onto the special photosensitive screen at the rear.
As time went by, the light spots on the photosensitive screen became more and more numerous and denser, but they did not appear as the reflection of two slits as they had imagined. The light spots were roughly distributed in nine strips... Although there were light spots in other areas, their number was very small.
"This is...is this interference fringes?!" Anthony looked at the scene in front of him with a look of astonishment on his face.
The rest of the wizards also found it incredible. Even the great wizards in the front row couldn't help but take a few steps closer to confirm up close that this was not an illusion and that there was nothing wrong with their eyes.
"Strange, why is this happening?" Vittorio frowned and muttered to himself.
"Hahaha, light particles are correct, my light particle theory is correct!" Sanchez shouted excitedly, this shows that particles can also produce wave phenomena!
"Idiot!" Anthony interrupted Sanchez. "If the electrons really pass through the holes one by one, then what affects their trajectory?"
Sanchez's laughter stopped abruptly, and he obviously realized this. His previous particle scattering experiment was successful because of the advantage of quantity. By making the particles in the two exploding element clusters collide with each other, he simulated a wave-like path.
The situation is different now. Electrons pass through the slit one by one, and normally they should not be disturbed. However, the fact is that these electrons deviate from their original direction.
It is as if there is a mysterious force that makes these electrons fall to these fixed points along a wave path.
Sanchez felt a chill on his back, wondering what was affecting these microscopic particles.
"Could it be that there is something wrong with the electron gun? In fact, it does not emit just one electron at a time, but many electrons..." A great wizard suddenly thought of this, but under the gaze of a group of wizards, his voice became smaller and smaller, and then it was directly interrupted.
After all, this was an experiment that directly questioned the Magic Star.
However, it seems to be a way of explanation to people very quickly, assuming that many electrons pass through the hole and then they affect each other.
Although this guess is outrageous and cannot explain why only light spots appear one by one on the photosensitive screen, and why the electrons happen to be on the same path as the wave trajectory, it is barely an explanation.
"Since everyone has doubts, why don't you all enter the magic network and I will take you to 'take a look' in person?" Lin En said with a smile, and then announced the magic method he had recently developed to connect to the magic network.
This is a very simple psychic magic. It is not difficult to use and can be used by any formal wizard.
In just a few minutes, the wizard in the exhibition hall had mastered this magic.
The reminder from the intelligent computer resounded in his mind, and more and more people were connecting to the magic network.
Even though most of the wizards had just connected to the magic network and could mobilize very little computing power, they were still overwhelmed by the large number of people and still managed to hold Lin En back...
The level of mental power also increased from seven to eight.
The strength of his soul could not keep up with the rapid growth of computing power.
Lin En took more than ten seconds to adapt, and then expanded his own domain to include the entire exhibition hall. Under the connection of the magic network, all the wizards present temporarily gained the ability to sense electromagnetic fields.
At the same time, within one tenth of a second, the thermal field emission electron gun emitted another electron.
Glenn, who was watching the experiment closely in the front row, instantly sensed the disturbance in the electromagnetic field. The disturbance was very small, but it was extremely clear due to the huge computing power provided by the magic network.
This 'electron' was lucky enough to pass through the gap on the right and hit the photosensitive screen, and a tiny spot of light appeared at the corresponding position on the screen.
"Really, there is really only one electron!" Anthony was extremely confused. Although they did not really see or sense the electron itself, they observed its general trajectory through the disturbance caused by this thing.
The particles do propagate in a straight line, and the light spots on the photosensitive screen at the rear are solid evidence.
But why did those strange interference fringes similar to those caused by waves appear? The wizards who were puzzled by this, like Anthony, were all very alert. They wanted to see with their own eyes what exactly affected the trajectory of the electrons.
The thermal field emission electron gun fired non-stop, and under the close watch of Anthony and others, every lucky "electron" passed through one of the gaps truthfully, without the slightest change in the path.
What about the deflection?
If this continues, how are the light spots similar to interference fringes formed? Anthony's expression became more and more confused, and at this moment a cry of surprise suddenly sounded in the exhibition hall.
"Look, the photosensitive screen... the photosensitive screen... has changed!"
Anthony's pupils shrank, and he noticed that at some point, the pattern on the screen had gradually changed from nine stripes to two...
Seeing this scene, even Harof, Vittorio and Aurora could no longer sit still. Their six eyes were fixed on the changing photosensitive screen, and then they turned to Lin En who was still sitting quietly in the judges' seat.
Lin En shrugged and said calmly, "You can see that my electron launcher is right there, and no one has touched it!"
