Question

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 What is the answer for this assertion reasoning question???

Answer 1

Answer: Both the assertion and reasoning are correct

Explanation:

Answer 2

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

Yes, the assertion is correct because as per the law of reflection of light upon incidence of light on a smooth surface the reflected light goes back into the same medium at an angle equal to the incidence angle.

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.

Yes , the reason is also correct. A parallel beam of light rays signify the fact that all the individual light rays have equal angle of incidence on to the smooth surface. As a result , all the reflected light ray have same angle of reflection and forms a parallel beam.

Hence , final answer is :

Both assertion and reason is correct but reason is not the correct explanation for assertion.
