When the light enters from air to glass, for which colour the angle of deviation is maximum?

Options

  1. ARed
  2. BYellow
  3. CBlue
  4. DViolet

Correct answer

D. Violet

Step-by-step solution

The refractive index of glass is the greatest for violet colour and is smaller for red colour and as ( -1) therefore deviation for violet will be maximum.
