Chapter 319 It seems that the speed of light is not very fast
In the evening of the next day, thousands of wizards and civilians gathered in an alley in Greenriel City, watching Glenn and others hang smooth mirrors on every wall of the street...

"There are only the last fifty mirrors left, and I will place them according to the drawings. The angles must not be wrong!"

Glenn loudly instructed Nancy and the others to put the mirror in a suitable place and adjust the angle according to his precise calculation.

It is also thanks to the wizard's steady hand and high precision. If the angle is [-] degrees, it will never be placed at [-] degrees. Otherwise, it is not easy to connect the reflected light of these hundreds of mirrors. things.

It took a whole day for the seven wizards to calculate the angles of refraction alone!

To Green's relief, the process of borrowing the mirror was very smooth. After knowing that it was used for the experiment of measuring the speed of light, many curious wizards generously donated the round mirror they had bought before.

He even got council approval to use the streets and squares of Greenriel City as a venue for experiments when the sun went down and shops closed.

It took more than an hour for Glenn and the others to arrange the last fifty mirrors. By the time they finished, the sun had already set and the entire city of Greenriel was pitch black.

At his request, there are no candles in all the houses, and everyone can only see the surrounding things clearly with a little moonlight.

"Glenn, can you tell me now? What are you asking us to borrow so many mirrors for? Are you planning to use this to measure the speed of light?" A wizard who was familiar with Glenn couldn't wait to ask.

Everyone present also had an expectant expression. Due to the temptation brought by the Silver Moon Medal, there are not a few wizards who want to complete this experiment. There are various ideas, but Glenn is the first to put his ideas into action. people!
Facing the eyes of everyone, Glenn also seemed a little nervous, but he continued to explain. "My plan is to use the principle that mirrors can reflect light to increase the distance traveled by light, so as to measure the speed of light..."

He placed a large number of mirrors in the city of Greenriel. Later, he will create a beam of strong light from the entrance of the DC area, reflect it all the way to the XC area through the mirror, and then go to the southern city area, and return in a circle...

"A total of [-] reflections are required, and the total distance is [-] kilometers!" Glenn said quite proudly.

He has accurately calculated every point where the mirror is placed, that is to say, they just need to stand in place and wait for the light to circle around the city of Greenriel, and the final landing point is the tower above their heads!
"I placed a white cloth on the top of the tower. As long as you see the conspicuous light spot on it, it means that the light has turned back a circle, and after running a hundred kilometers, you can calculate the speed of light by using the time it takes to reverse it... ..." Glenn explained.

"It's such a novel idea, it can still be like this..." Raphael suddenly realized, and looked at this wizard named Glenn in admiration. In this way, it only needs to use a few streets to create a distance of [-] kilometers. Experiment under their noses.

The rest of the wizards also immediately became interested. Glenn's plan still sounds very feasible. It is a full hundred kilometers. After all, the light element needs to run for a second or two, right?
"Dean Lynn, do you think this can measure the speed of light?" Eloque couldn't help asking, but he knew that the dean is also preparing related experiments recently, which will determine a Silver Moon Medal belong.

"It's feasible, but it's not feasible..." Lin En smiled and said mysteriously, without revealing the answer.

I have to say that Glenn is quite creative. He can even think of this method, but he still lacks some considerations...

Seeing the ambiguity of what Lynn said, the wizards on the field couldn't help curling their lips. It seems that even the star of magic doesn't know the result, so they can only use this excuse to save face.

But that's right, if the other party knew in advance, I'm afraid they would have measured the speed of light... After all, this experiment is not complicated, as long as there are enough mirrors, it can be easily reproduced.

Glenn didn't try to argue with everyone's words. He took the blueprint in his hand to confirm it for the last time, took a deep breath, and adjusted his state.

Time passed bit by bit, and when it was almost three seconds before zero o'clock, Glenn raised his hand, and a scorching fireball emerged in the air, illuminating the entire street.

But this was just the beginning. Glenn and five other wizards cast spells together. Under the surge of magic power, circles of reflection layers began to appear around the fireball, forming a closed sphere in midair, covering the fireball. Inside, only a small hole with a diameter of one centimeter was left...

The light released by the entire fireball was gathered together and shot out through the small hole, and the target was the first round mirror.

Glenn controlled the time extremely precisely, and it was the moment when the magic clock reached zero. In the eyes of countless people, dazzling beams of light appeared in the entire street, which stretched to end of view.

On the side, Nancy turned her back to Glenn, her eyes were only fixed on the top of the tower, she didn't dare to blink at all, for fear of missing the spot of light, she was holding a magic clock in her hand, the moment she saw the spot of light, she It must be stopped immediately, and the final time is the time it takes for light to travel through one hundred kilometers.

One second...three seconds...five seconds...ten seconds...

Nancy's eyes were sore from staring, but there was nothing on the white cloth on the tower, and there were no spots of light.

"It seems that the speed of light is not very fast... It's been more than ten seconds, why hasn't it arrived yet." Eloque said with a mutter.

"This is a full [-] kilometers, no matter how fast it is, it still takes half a minute?" Pierce said with a smile.

Raphael and the others frowned, and a thought vaguely appeared in their minds. Could it be that something went wrong with the experiment?
Thinking in this way, several great wizards flew up directly, intending to look around the whole city from a high altitude, looking for the problem.

Glenn below also noticed that something was wrong, because the light intensity weakened much faster than he expected when reflected by the mirrors he saw several times...

About ten seconds later, Rafael and the others returned from the air, the expressions on their faces becoming somewhat helpless.

"Master Raphael, how is the situation? Has the light not arrived yet?" A friend of Glenn hurried forward and asked curiously.
