Question

_____ is a measure of amount of deviation of the incident ray from its usual path.

  1. Angle of dispersion
  2. Angle of deviation
  3. Angle of the prism
  4. Angle of refraction

Hint:

So the angle of deviation is equal to the angle between the incident ray and the refracted ray of a prism.

The correct answer is: Angle of deviation


    • The angle of deviation is the measure of the deflection of the incident ray of light from its original path after it has been refracted from the surface of a prism. So the angle of deviation is equal to the angle between the incident ray and the refracted ray of a prism.
