The strange light dispersion experiment aroused everyone's curiosity. They never knew that light was composed of so many colors.
Or is it that only artificial light has such characteristics? "Whether it is this light or sunlight, of course they are the same, both belong to complex color light." Lin En explained to the curious Alok and others.
The principle of prism light splitting is that different colors of light have different refractive indices in glass, so when passing through the prism, each color of light is deviated in one direction, which forms a gradient spectrum...
A group of wizard apprentices listened thoughtfully. Lynn's explanation was very easy to understand. Even people like Redel who didn't know magic could barely understand it.
"Wait, I think I've seen this thing before..." Ham stared at the colorful light reflected from the prism, his face thoughtful, and then suddenly spoke. "Yes, it's like... a rainbow?"
After Ham said this, more and more people reacted. Although the rainbow phenomenon was not very common, many people had seen it.
"Is there a mirror in the sky?" Lydia asked, raising her hand high.
This time, Philip explained without waiting for Lynn to reply.
"It should be the refraction and reflection of water, right?"
There was a lot of water vapor in the air, which every wizard knew very well, and the water surface also had the ability to refract and reflect light, so Philip instantly understood its principle.
"Not bad!" Lin En nodded, and then handed the prism in his hand to Lydia. "As for the other properties of light, I'll leave it to you to explore."
Lydia took the prism excitedly, placed it under the light and kept rotating it. The light kept flowing and reflecting in the prism, changing its size and color.
Alok and the others looked at Lin En eagerly. The dean just handed the only prism to Lydia. What should they do? Don't wait for such partiality! "Glass is not difficult to make. You also know the formula. I taught it in chemistry class. If you want, can't you just make one yourself? Studying the spectrum of the sun is also your homework for going out!" Lin En shrugged and spoke freely.
When they heard about the homework assignment, Alok and the others' faces immediately drooped, and they tried hard to recall the chemistry class that Lin En had taught them some time ago.
What is the main component of glass? Silicon dioxide, I think?
"I heard that there are many wizards in the city of Greenriel who are studying the mystery of light. Even the Speaker is very interested in it. You have a lot of opponents!" Lin En added.
Although the wizarding land has been busy with war matters recently, the parliament still pays great attention to academic research. After all, this is the foundation of all magical power.
As glass products gradually became more popular, more and more wizards have discovered their uses in research. For example, the simplest convex mirror can make objects appear larger or smaller in one's eyes.
This means that wizards no longer have to rely solely on magic to perceive things, but can use their naked eyes to directly see the previously invisible microscopic world!
Lin En had no doubt that after this war, the theory of "magic" in the entire wizarding land would usher in a leap forward! When they heard that many wizards, even the legendary Speaker, were studying this, the apprentices suddenly felt that they had no hope.
"By the way, Professor Philip, how is your research on the electromagnetic cannon going?" Lin En suddenly remembered this, turned to look at several people and asked.
"The principle has been figured out and the model has been made, but its power is somewhat unsatisfactory. It can only launch a 100-gram projectile at a speed of 100 meters per second." Philip said helplessly.
The generator they made is fine for lighting a light bulb, but it is too weak to be used in an electromagnetic gun. If there is not enough electricity, this thing is not as useful as a cannon.
Lin En was not surprised by this. The generator would need to be improved for at least several generations before it could meet the needs of the electromagnetic gun. After thinking about it, he asked someone to bring a basket of black stones and a plate.
"This is a lightning stone and several magic runes representing electromagnetism. You can study how to use them!" Lin En explained.
Since the old method doesn’t work, why not try a new approach?
These two things are the results of Anthony's research for most of his life. The lightning stone is like a natural battery, and it is a super-powerful one, and these electromagnetic runes are the key to converting magic power into electric current!
When Phillip and others heard this, their eyes suddenly brightened.
In this way, they can store all the excess electricity on weekdays, and find a way to export it when they need to use the electromagnetic cannon. They can even use lightning-inducing stones as the material of the guide rails, coat the outside with a layer of mithril, and engrave electromagnetic runes...
In just a dozen seconds, many ways to improve the electromagnetic gun emerged in Philip's mind, and many difficulties that had troubled him in the past were directly solved!
Thinking of this, Philip said goodbye in a hurry, took a few colleagues with him and went to do research with a basket of lightning-inducing stones.
The huge light bulb stayed on in the castle for the entire night. This was both a test of the sample and something Lin En did intentionally.
So much so that early the next morning, rumors about the electric light spread rapidly throughout the earldom, and then became more and more outrageous. Some people swore that they saw with their own eyes the wizard flying into the sky, grabbing lightning and a huge rainbow from the clouds and putting them into a ball and a gem!
Lin En did not make any blunt excuses for these rumors. Instead, he assigned a new task to the Musketeers who went out for training every day. That was to use water mist to create an artificial rainbow in the square, and he taught this method to every curious child who wanted to learn.
The change of concepts is often subtle. Lynn wants to let these people know that wizards are not scary, and the knowledge they spread is not a trap of the devil, but an explanation of the laws governing the operation of all things. Even ordinary people can understand and apply it!
The next question is how to solve the last obstacle to their control of the kingdom—the Cardinal Ansruch of the church!
