Question

37. Assertion: Incident light is reflected in
only one direction from a smooth surface.
Reason: Since the angle of incidence and
the angle of reflection are same, a beam of
parallel rays of light falling on a smooth
surface is reflected as a beam of parallel
light rays in one direction only.
​

Answer 1

Both assertion and reason are true.

As the law of refection of light states that the angle of incidence of light is equal to the angle of refection of light.

Explanation:

Assertion: Incident light is reflected in  only one direction from a smooth surface.

Reason: Since the angle of incidence and  the angle of reflection are same, a beam of  parallel rays of light falling on a smooth  surface is reflected as a beam of parallel  light rays in one direction only.

Both assertion and reason are true.

As the law of refection of light states that the angle of incidence of light is equal to the angle of refection of light.
