Question

When the light ray is ___________ to the boundary between two medium, light does not bend.

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

Answer 1

The correct option is A

normal

(i)

Light falls obliquely $(i\ne 0^{\circ })$

(ii)

When a light ray falls on the surface normally, then refraction occurs but it does not bend the light. Only, the velocity in the second medium changes.
