What did Isaac Newton use as a source of light to shine at a prism?

Answer 1

Sir Isaac newton fond that a white light is made up of 7 basic colors {vibgyour} of different wave lengths. In order to prove this he rotates the 7 colour band disc with a speed of 44.6 m/sec he saw that in the of rotating the colourfull CD becomes white.

Answer 2

One day he bought a prism at the Stourbridge Fair. (This is a piece of glass shaped like a triangle.) He had it sitting on his desk, and noticed how when the sun shone on it, he got different colors out. This made him very curious. Does this change the light, or does the sunlight have lots of colors that the prism puts into different places? How does the prism do it? To find the answers, Newton had to do some experiments. He first used his blinds to get a very thin sunbeam to hit the prism. This was important - to control the light that was coming in so that he knew exactly what he was starting with. He discovered that the separation of light was even clearer. There was red, then orange, then yellow, then green, and then blue. Newton was pretty sure that what was happening was that the light from the sun had all these colors in it, and that what the prism was doing was bending them all to go into slightly different directions. To test this he got two prisms and a card with a hole in it. He used the first prism to get the sunlight to make different colors. Then he would choose a color and put the hole so than only that color went through into the next prism. He then had a very thin line of red, yellow or some other color of light going to the second prism. He discovered that when the light came out of the other side of the next prism, it was still the same color as when it went in. So the prism doesn't change the light's color. What the prism did do was to bend the path the light went on, so that it hit a different place than when the prism wasn't there. When he tried different colors of light he found that the prism bent them all a little bit differently. That was why light that looked white, which had all the colors in it, made different colors when it went through the prism - the different colors all came out of it in slightly different directions.

Answer 3

The three basic laws of motion:

1st law- Law of Inertia: An object in motion will stay at the same speed and direction unless acted upon by an outside force. An object at rest will stay at rest unless acted upon by an outside, unbalanced force.

2nd law: Acceleration is produced when a force acts upon an object. The greater the mass of the object, the more force it takes to move it.

3rd law (the simplest): Every action has an equal and opposite reaction.

Answer 4

Newton used a telescope to study the light, then Newtons experiments became really dangerous because Newton looked at the sun and he ruined his eye sight but then a couple of months later he got his eye sight back.

Answer 5

he found that light could be seen in water

Answer 6

i dont really know but i think he was finding about the directions of the lights

Answer 7

Newton used Sunlight

Answer 8

A prism is a long triangle of solid glass. It has no light source of it's own. What ever light strikes the long side is it's light source, such as sunlight.

Answer 9

Sir Isaac Newton purchased a glass prism of unknown origin to use in his experiments. He is credited with naming the colors of the prism - including rainbows.

Answer 10

a triangular prism
