Refraction of Light
  • 1. The diagram shows a ray of light AB striking the interface of medium X and medium Y. BC is the refracted ray. Which one of the following statements is correct?
A) Medium X is optically denser than Y and ray BC travels slower than AB.
B) Medium X is optically denser than Y and ray BC travels faster than AB.
C) Medium X is optically less dense than Y and ray BC travels slower than AB.
D) Medium X is optically less dense than Y and ray BC travels faster than AB.
  • 2. When light passes from one medium into another, refraction occurs. This is because of
A) a change in velocity of the light.
B) the absorption of light.
C) a change in colour of the light.
D) the reflection of light.
  • 3. A light ray does not bend at a boundary between two media of different optical densities if its angle of incidence is
A) 45o
B) 90o
C) 180o
D) 0o
