"I'm afraid it will be difficult to continue this experiment!"
"Master, what's going on? Could it be that the refraction angle of the light is wrong?" Nancy asked anxiously. However, they had confirmed dozens of times that every mirror was carefully placed according to the blueprint.
But before Raphael could answer, Glenn sighed and said, "Maybe the light has become weaker?"
"That's right!" Raphael nodded. "I just checked in the air. The light beam you created has become so weak that it cannot be recognized by the naked eye after being reflected by the seventy-third mirror..."
"It's decaying so quickly?!" Glenn's face turned pale. If the light could penetrate three or four hundred mirrors, there might be a way to make up for it. All he needed to do was find a few more wizards to cast spells together and create a more powerful light beam.
But there are only seventy-three mirrors, and they have only covered one-fourteenth of the distance. With such an attenuation frequency, they have to strengthen the beam ten times or even a hundred times? How is this possible?
"Master Lin En, I think you should know what's going on?" Raphael turned to look at Lin En and asked.
Everyone present turned their eyes to the Magic Star and immediately remembered Lynn's comments on the experiment.
Possible, but not feasible...
Lin En didn't keep the secret any longer and started to explain. "It is possible to use the principle of reflection to make light travel a longer distance. However, although the mirror can reflect light, it cannot reflect it completely. It will inevitably lose some energy every time..."
"In other words, we should reduce the number of mirrors and increase the distance of each reflection?" A wizard quickly thought of a solution.
"No, that won't work at all," Glenn sighed. "Light can't travel very far."
He had already tried this before, so he reduced the distance between the two mirrors to about a hundred meters.
"That's because the elements in the air also reflect and absorb light, and the light itself does not propagate in parallel, but diffuses in all directions, so we can see the light..." Lynn continued to explain.
In other words, as long as they can see the light, it means that the light is dispersed and reflected into their eyes... Raphael immediately understood what Lin En meant, but then suddenly retorted.
"This shouldn't be right. Then how can the sun's light travel thousands of kilometers to reach this eternal star?"
After Raphael's reminder, many wizards also discovered the "loophole" in Lin's words. If the light is constantly attenuating, then the light from the sun cannot reach here!
The wizards of the Prophecy School have calculated the distance between the Eternal Star and the Sun. It is an astonishing value. Even the closest point is hundreds of millions of kilometers away! "Outside our planet, in the vast universe, the content of elements is very rare, and light does not lose energy in a vacuum. As for when it reaches this planet, it is just scattered and absorbed by the elements, not disappeared..." Lin En shook his head and said.
Lynn's answer dispelled everyone's doubts, but the series of problems left Glenn and others completely stunned.
In this case, the problem of light intensity attenuating with distance cannot be solved. Glenn thought hard for a while, but he couldn't think of how to make the light cross a distance of 100 kilometers and still be seen by them...
It is conceivable that they will become the laughing stock of wizards' gossip tomorrow.
At this moment, a voice like a loud bell suddenly rang in everyone's ears. "Then why don't we make these troublesome elements disappear, create a large enough vacuum area, and simulate the environment of the universe?"
Everyone present looked in the direction where the voice came from, and then found that several legendary Speakers were walking towards them, and the one who spoke was Harov!
"Lord Harof!" Glenn was surprised.
Yes, as long as we create a vacuum area that covers the distance that light propagates, we can greatly reduce the degree of reduction in light intensity.
Only a legendary wizard like Harof could come up with this outrageous, yet very effective solution!
After Harrof spoke, the wizards gathered nearby also offered advice to Glenn.
For example, a thousand mirrors are too many. They can increase the distance of each reflection by one kilometer, so only a hundred mirrors are needed! Even Anthony stood up. He was very interested in the experiment of measuring the speed of light with mirrors, and took the initiative to suggest that he could use thunder magic to create a more powerful light source...
Amid the lively discussions among the crowd, one problem after another was solved. Such an enthusiastic magic research atmosphere also made Lin En feel very comfortable.
Although there were many people on the scene who were just watching the fun or even waiting to see the joke, there were also many wizards who were concentrating on magic research and wanted to figure out how fast the speed of light was.
Glenn also cheered up again, modifying the position and angle of each mirror on the blueprint, and reduced the number to 100, preparing to do another experiment with the help of more powerful light! "Everyone who is not related should step back first, and all the great wizards should stay!" Harov said solemnly. Even if he was a legend, he could not do such a large-scale repulsion of elements. He had to gather the strength of everyone.
The preparations took another hour to complete.
Anthony took the lead. Flashes of lightning began to appear in his palms, and they became brighter and brighter. The violent thunder continued to leap. Both civilians and wizards squinted their eyes. The light was so bright that it was impossible to look directly at it...
"Let's start!" Harrov raised his voice a little, and his voice spread to every corner of the city.
At the same time, twenty great wizards and three legends cast spells together. The elements that kept surging around them were quickly repelled under the influence of huge magic power. In just three seconds, a vacuum field covering half of the city had quietly taken shape!
"What a grand deal..." Lin En said with emotion. The wizards' imagination and practical ability far exceeded his expectations, but he quickly gathered his thoughts, raised his hands to specifically expand his own territory, and completed the vacuum section that he was responsible for.
