Question

What is Newton's Colour Disk? What is its appliance?​

Answer 1

Answer:

The Newton disc, also known as the Disappearing Colour Disc, is a well-known physics experiment with a rotating disc with segments in different colors (usually Newton's primary colors: red, orange, yellow, green, blue, indigo, and violet or ROYGBIV) appearing as white (or off-white or gray) when it spins very fast.

this experiment shows that white light is not made up of white colour but it is made of many other constituent colours
