Question

name the colour that will be reflected when following colours of light strike the given coloured surfaces.

Answer 1

****************white colour

Answer 2

In blue and yellow objects the blue and yellow light rays would reflect as it is because the objects seen in blue and yellow are reflecting the same colors respectively. But if the surface is green and the light have all the colors of spectrum (i.e. white) it would reflect only green light and would absorb all colors except green.
