Newton's Color Disk

Newton

• He was the fisrt to show the natural laws as: the movement of the earth and, the moviment of bodies are the same.
• He discovered the color spectrum.

Light:

• In the years 1670 to 167, he worked with problems related to optics and the nature light, and he desmostrated that the white light was composed by a band of colors as: Red, yellow, green, blue and violet. These could be separated in a prism

Experiments:

• Add a second prism, inverted respect to the first, and so that the beam of the ligtht is back together again to form a white beam.
• The "disk of Newton"

The disc of Newton

• It's a roulette wheel that is divided i seven sectors, each painted with one of the colors of the rainbow.
• In so doing turn a hight speed, and then the appearence of the disk will be white

The color disc of Isaac Newton, demostrates that the white light is formated by the colors of the rainbow. He found light passing through a prism, the light is composed of series of brilliant colors called "solar spectrum".

Conclusion:

• The purpose of the disk is rotating with the disk quickly, making us see the color white, as a mixture of all the colors of the rainbow
