PHYSICS [2 Mark Question Answer]

The process of color subtraction is a useful means of predicting the ultimate color appearance of an object if the color of the incident light and the pigments are known. By using the complementary color scheme, the colors of light that will be absorbed by a given material can be determined.

When a ray of light falls normally on the surface of a plane mirror, the incident ray is reflected back along the same path. This is because the angle of incidence is zero, so the angle of reflection will also be zero.
