Question

The deviation produced by an equilateral prism, when a ray of light is incident on it, does not depend on :

• A. angle of incidence
• B. colour of light
• C. material of prism
• D. size of prism

Answer 1

The correct option is D size of prism

Correct answer is (d)

Equilateral prism is a wedge-shaped body made from a refracting medium bounded by two plane faces inclined to each other at some angle, in which plane faces are called the refracting faces and the angle included between these two faces is called the angle of prism or the refracting angle. The deviation produced when a light ray incident on it depends on incidence angle, colour of light indirectly the wavelength and on the material used in making prism while it doesn’t depend on the size of equilateral prism.
