Question

White colour object will look red in ______________ colour light.

Answer 1

The white object will look red because the white surface reflects all colors and since only a red light is used it will only reflect red.

Answer 2

Explanation:

Red light is the only light that is reflected from the shirt. If only blue light is shone onto a red shirt, the shirt would appear black, because the blue would be absorbed and there would be no red light to be reflected. White objects appear white because they reflect all colours.
