Question

In order for us to see the red apple, where do the wavelengths of light have to go?

Answer 1

A red apple appears red because when white light illuminates the red apple all of the colors in

the white light are absorbed except the red light which is reflected. Since blue light one of the primary colors (and does not contain red light), when it illuminates a red apple the apple would appear black since there is no red light to be reflected back.
