What is the shadow?

"What. Is not it? I'm saying. The light goes on a straight line. When there is obstruction in any object in front of this movement, a dark effect is formed on the opposite side of the object, which is called shadow. "

"I understand this definition too. What is new here? It was just getting late from the stomach, this is what it is. "I am asking, why should not I? "Well, Professor, because the light is obstructing, even then the object can be seen through the shadow. How do I see objects when there is light? "

"The light is obstructing but the light from the other side of the object is coming? That's why the shadow does not look completely black. "" So the color of the shade just black? "

Color shade!

"The colors of the shade can be different. But it is usually not seen. The shadows of different colors can be seen only when light of more than one different color illumines the same layer. If you put objects in front of those lights, then shades of different colors can be seen. One day I will show you in your hands. This test is very easy. "(Post-details will be posted later)

He also said, "There is a shadow but speed. This speed is equal to the speed of light. "

"How does shadow speed equal to the speed of light?"

"The shadow is created in the absence of light. Do you think you light the wall. This light is 3 lakh km / ha Going at the speed. If you stand in front of the light, you will stop going in front of the light. Then your shadow will be created. This shadow will be created at the speed at which the light stopped coming.

Again, there are some examples that may seem like shadow speed is more than light. For example, think that you have a very strong light source on the moon. And move your finger in front of the light. If your finger is to move a few kilometers in the direction of a semiconductor chad. Because the shadow on the surface of the light will be made, the shade of the distance from the floor will be as big as the distance from the object, the proportion of the shadow size. However, this comparison can not be taken in scientific terms. Because the shadow does not exist like light. That means light is made of photon particles. But the shadow is not made of any substance. And besides, you move your fingers in front of the light. From the earth, the earth actually moves your finger just 1 cm "

"Wow is pretty funny"

The shadow of the earth proved to be round

"There are more. With the shadow possible to prove that the earth is not round, flat. Eratsthenis has proved that. At midday when the sun is at the top of the head 90 ৹ in the corner, but there is no shadow of the object like a smooth rod. If the stick stands vertically at 90 ৹ corner. Because, at that time, the light of the sun gives a light on the ladders, so the light is full of light. If there is light everywhere it will not be able to create shade. Based on this incident, he did the test.

He learned from Papyr's book that on 21 June, the shadow of the object merged into mediate. Araratsthenes wanted to know through a test whether he had a vertical stick shade in the middle of June 21 in Alexandria. After the test, he discovered that the stick was shadow.

Eratosthenes himself questioned how, at the same time, a stick does not reflect shade in Sainan and the stick in Alexandria, which is located north of many north, reflects clear shadows. Consider a map of ancient Egypt, where the two vertical vertical sticks, one is installed in Alexandria and the other in Sainte Suppose no stick is throwing a shadow at a particular moment. It would have been easy to understand if the surface was flat. Then the sun stood on the steep head. If two sticks gave the shadows of the symphony, it also showed the concept of a flat surface. Then the sun-ray was in the same corner of the two corners. But how did it happen that at the same time there was no shade available in Saiyan, but in Alexandria there was enough shadow available?

Erotesthenes realized that, the only possible answer is that the surface of the Earth curve. Not only that, the higher the curvature, the greater the length of the shade. The sun is so far from the earth, that when its rays arrive at the surface, it remains parallel. "

"Do not the flatists know this information? From this it is easy to prove that the Earth is curved. Is round. "

There is a shadow of fire!

"They basically ferry false information for interest. They also know the truth. There are many misconceptions about this incident of shadow. A few days ago I saw a forum, one question is why the shadow of the fire can not be seen? Several have answered the shadow of the fire because it is a source of its own. But a different answer answered. She said that the shadow of the candle is seen in the shadow, which means that there is a shadow of fire. That's wrong but it's wrong. Because the density of fire is very low. He does not have enough power to stop him from lighting. As a result, the shadow of ordinary gas can not be seen. But the candle contains carbon. During the burning of candles, carbon fumes continue to be prepared. Since carbon is heavy, it can prevent light. As a result, shade of flame is made. "
