I made science magic

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 outside a street in Greenriel City, watching Glenn and others hang smooth mirrors on every wall in the street...

"Only the last fifty mirrors are left. Place them all according to the drawings. The angles must not be wrong at all!"

Glenn loudly directed Nancy and others to place the mirror in a suitable place and adjust the angle according to his precise calculations.

Thanks to the wizard's steady hands and high precision, if the angle is said to be fifteen degrees, it will never be 16 degrees. Otherwise, it would not be easy to connect the reflected light of these hundreds of mirrors in series.

things.

Just for the various refraction angles, it took the seven wizards a whole day to calculate them together!

What made Green feel a little relieved was that the process of borrowing the mirror went very smoothly. After knowing that he was used for the light speed measurement experiment, many curious wizards generously donated the round mirrors they had bought before.

He even received approval from the council, allowing him to use the streets and squares of Greenrial City as a venue for experiments when the sun went down and the shops were closed.

It took Glenn and others more than an hour to place the last fifty mirrors. By the time they were finished, the sun had set and the entire Greenriel City was pitch black.

At his request, there was no candlelight in all the houses, and everyone could only see the surrounding things clearly with a little moonlight.

"Glenn, can you tell me now? Why are you asking us to borrow so many mirrors? Do you plan to use these to measure the speed of light?" A wizard who was familiar with Greene asked impatiently.

Everyone present also looked forward to it. Due to the temptation brought by the Silver Moon Medal, there were many wizards who wanted to complete this experiment. There were various ideas, but Glenn was the first to put his ideas into action.

people!

Facing the attention of everyone, Glenn also seemed a little nervous, but he still explained eloquently. "My plan is to use the principle that mirrors can reflect light to increase the distance traveled by light, thereby measuring the speed of light...

"

He has placed a large number of mirrors in Greenriel City. Later, he will create a beam of strong light from the entrance of the DC area, reflected by the mirrors all the way to the XC area, and then to the Nancheng District, and then return in a circle...

"A total of one thousand reflections are required, and the total distance is one hundred kilometers!" Glenn said proudly.

He has accurately calculated every point where the mirror is placed, which means that they only need to stand there and wait for the light to circle around Greenriel City, and the final landing point will be the tower above their heads!

"I placed a piece of white cloth on the top of the tower. As long as you see a conspicuous light spot on it, it means that the light has made a circle and traveled a hundred kilometers. The speed of light can be calculated by inferring the time it took...

..." Glenn explained.

"What a novel idea, it can actually be like this..." Raphael suddenly realized and looked at the wizard named Glenn with admiration. In this way, he could create a distance of a hundred kilometers with just a few streets.

Experiments are being done right under their noses.

The other wizards immediately became interested. Glenn's plan sounded very feasible. It was a full hundred kilometers. After all, the light element would need to run for a second or two, right?

"Dean Lin En, do you think this can measure the speed of light?" Alok couldn't help but ask. He knew that the dean was also preparing related experiments recently, which would determine the price of a Silver Moon Medal.

Belong.

"It's feasible, but it's also not feasible..." Lin En smiled and said mysteriously, with no intention of 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 that Lin En's words were so ambiguous, the wizards on the scene couldn't help but curled their lips. It seemed that even the magic star didn't know the outcome and could only use this excuse to save face.

But that's right, if the other party had known in advance, they would have measured the speed of light long ago... After all, this experiment is not complicated. As long as there are enough mirrors, this experiment can be easily replicated.

Glenn did not interpret what everyone said. He took the drawing in his hand and confirmed it one last time. He took a deep breath and adjusted himself.

Time passed bit by bit, and when it was almost three seconds before midnight, Glenn raised his hand, and a hot fireball emerged in the air, lighting up the entire street.

But this was just the beginning. Glenn and five other wizards cast spells together. Under the surge of magic, circles and circles of reflective layers began to appear around the fireball, forming a closed sphere in mid-air, 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, targeting the first circular mirror.

Glenn controlled the time extremely accurately. This was the moment when the magic clock reached zero. Under the attention of countless people, dazzling beams of light appeared in the entire street, which continued to stretch under the constant reflection of the mirror.

The end of the field of vision.

On the side, Nancy had her back turned to Glenn, her eyes were just staring at the top of the tower, not daring to blink for fear of missing the light spot that appeared. She was holding a magic clock in her hand. The moment she saw the light spot, she

It must be stopped immediately, and the final time taken is the time it takes for light to travel one hundred kilometers.

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

Nancy stared so hard that her eyes were sore, but there was nothing on the white cloth on the tower, and no light spots appeared.

"It seems that the speed of light is not very fast... It has been more than ten seconds, why hasn't it arrived yet?" Alok muttered.

"This is a whole hundred kilometers. No matter how fast you run, it still takes half a minute, right?" Pierce said with a smile.

Raphael and the others frowned, and a thought vaguely emerged in their minds. Could it be that there was something wrong with the experiment?

Thinking like this, several great wizards flew up directly, intending to look around the entire city from a high altitude to find the problem.

Glenn below also noticed something was wrong, because the light intensity weakened much faster than he expected when reflected from several mirrors he looked at...

About ten seconds later, Raphael and others returned from the air, the expressions on their faces becoming a little helpless.

"Master Raphael, how is the situation? Has the light not arrived yet?" One of Glenn's friends hurriedly came forward and asked curiously.
