Question

No refraction occurs when the light is incident normally on a boundary between two media.

• A. normal
• B. parallel
• C. obliquely
• D. curved

Answer 1

The correct option is A

normal

Refraction takes place at the surface separating the two media when light passes obliquely from one medium to another medium of different optical density. No deviation takes place in the case of a light ray falling normally on a medium i.e., no refraction occurs when the light is incident normally on a boundary between two media.
