Lydia waved her hands and shouted loudly on the high ladder placed on the open space. The reason why the light bulb was placed so high was naturally so that everyone could see it! "Let's start!" Lin En nodded, looked at Alok and others beside him, and asked them to start the motor.
The sound of "thump thump thump" immediately resounded in the castle, scaring the poor people who were watching from afar.
This motor also uses the principle of cutting magnetic lines of force, and is not protected by a casing. Everyone can see the tiny electric arcs flashing around the motor's rotor as it moves at high speed.
A steady stream of electric current is being transmitted to the light bulb through the wires.
Dozens of fire lion hairs inside were intertwined and twisted into a spiral shape, emitting a faint light.
After a while, the light became brighter and brighter, soon overshadowing the faint light from the surrounding torches, illuminating the entire open space like daylight.
Redel and others who were looking directly at the light source had to squint their eyes or subconsciously put their hands in front of them under such a strong and dazzling light. It felt like they were looking at the midday sun.
"Lightning, they trapped the lightning in that ball!" Someone in the crowd of onlookers shouted in a trembling voice.
Ham and the others were all looking in amazement at the light bulb that was emitting bright light in the air, and then at the motor that was constantly turning.
They had thought about what methods the wizards would use to make the night as dark as day, but they had never expected that their method would be to bind the lightning! The light from the bulbs spread far away, and the poor people hiding in the houses could not help but look through the windows at the open space where the crowds gathered. It was like a small sun rising here...
Lin En was also very satisfied watching this scene. They had verified it in the laboratory before, but this should be the first experiment conducted outdoors.
This was their first step into the electrical age! The performance of the Fire Lion's hair was much better than Lin En expected. The only drawback was its short lifespan. According to his estimation, even the hair plucked from the Fire Lion would not last for half a year and would be burned by the high temperature.
Of course, in a sense, that's not a disadvantage...
Moreover, compared to tungsten filament, this biological material is extremely environmentally friendly and can be infinitely regenerated...
"It seems that there will be no more dark nights in Yieta in the future." Philip said with emotion. The materials used to make this kind of light bulb are not complicated, and there are also many magnetic ores in the Kingdom of Hadhrata. He can foresee that in the near future, lights will illuminate every corner of the city.
"It's like a little sun!" Redel murmured.
"It's still a long way off. The real artificial sun would be thousands of times more dazzling than this!" Lin En said with a smile.
Hearing this, everyone present looked at Lin En with strange expressions. It sounded as if they could really create a sun.
"So light is electricity and electricity is light, right? Professor Lin En?" Johnny on the side pondered for a long time and suddenly asked.
They introduced electricity into the hair of the fire lion to create light. Is that the same way they feel the light every day? This question stumped Philip and other formal wizards for a moment. Everyone frowned and pondered.
"That shouldn't be right, right? Light and electricity manifest themselves in different forms, and we can create light in other ways." Orlando shook his head and raised his hand to form a fireball. "For example, can we say that fire is light?"
However, the 'light element' is extremely difficult to deal with. It seems to be everywhere, yet elusive and cannot be sensed with magic power at all.
However, they still summed up a lot of rules, such as light is often born with heat, can be reflected, absorbed, etc., and developed a lot of magic using light.
"You have a good idea, Johnny, but you have to find the secret yourself!" Lynn couldn't help but laugh, but he didn't mean to give a direct answer. After all, the exploration of the laws of the world must be done step by step, and both the right and the wrong must be tried before a truly complete magic theory can be developed.
“Whoever among you can thoroughly study light, no, even if he or she only understands the basics, will be awarded a Corona Medal and leave a mark in the history of magic!” Lin En said solemnly.
Corona Medal?
Hearing what Lin En said, Alok and the others were all very excited. That was the highest award in the magic world! Even Lydia was a little eager to try. She had no magical talent and it would be difficult for her to pass the formal wizard exam, but this did not prevent her from becoming the first wizard apprentice to receive the Corona Medal!
"Professor? Then where should we start exploring the secrets of light?" Lydia asked anxiously.
Orlando laughed. If the dean knew about this, he would have brought it up long ago and would have left them the opportunity.
However, to his surprise, Lin En took out a crystal clear glass from his pocket and shook it in front of everyone.
“You can start with this!”
"Dean, isn't this just an ordinary piece of glass?" Alok curled his lips.
Glass products may be very precious in the Kingdom of Hadhrata, but in Iyeta even ordinary civilians can afford them. When expanding the school, they even planned to put them on the windows for better light transmittance. There is nothing special about it.
"To be precise, this is a prism!" Lynn explained with a smile, and placed it under the light. Only then did everyone present notice the difference.
This prism looks like a fine gem. Light enters from one side of the prism and exits from the other side after being refracted. However, the refracted light is not bright white, but an extremely gorgeous gradient of seven colors: red, orange, yellow, green, cyan, blue, and purple. It is extremely dazzling when projected into the shadow...
Alok and others looked at the scene in front of them in amazement.
The light... was actually separated! "The white light we saw was so beautiful!" Lydia said in surprise and delight.
"Professor, what is the principle behind this?" Pierce stretched out his hand and moved it back and forth on the spectrum. The colorful light shone on his palm, and he felt a little warm.
"Is this a phenomenon only seen in light generated by electricity? Or does it happen in all light?" Philip on the side asked anxiously.
