Question

A white light is allowed to fall into the white screen. Between the screen and the source of light there are two filters. The first filter near the source is magenta filter. if the screen is seen blue, what is the second filter near the screen? (PLEASE HELP ME OUT. THE ASSIGNMENT IS DUE TOMORROW)

Answer 1

Answer:

For this reason, the filter will appear magenta (recall that magenta light is a mixture of red and blue light) when illuminated with white light.

Explanation:

When white light shines on a red object, all of the colors that form the white light are absorbed except red, which is reflected. ... So when blue light is allowed through a blue filter onto a blue object, the object will still reflect blue and therefore appear blue.
