What is Newton's Disc?

This is a type of disc that is divided into the rainbow colors (red, orange, yellow, green, blue, indigo and violet).

How does it show that light is composed of many colours?

When the Newton disc is spun, it produces a white light. This means that light is made up of rainbow colors.

Explanation:

Newton's disc is commonly used in experiments. This is an idea introduced to us by Isaac Newton, an influential scientist who greatly contributed to science. The disc is described as a color wheel, in which the different rainbow colors are shown. Once you spin the wheel, you'd be able to see the different colors blending in. It turns into one color and that is "white."
