Assertion $ (A) $ : In the case of a rainbow, light at the inner surface of the water drop gets internally reflected.
Reason $ (\mathrm{R}) $; The angle between the refracted ray and normal to the drop surface is greater than the critical angle.
(A) Both Assertion and Reason are true and Reason is the correct explanation of the Assertion.
(B) Both Assertion and Reason are true but Reason is not a correct explanation of the Assertion
(C) Assertion is true but the Reason is false
(D) Both Assertion and Reason are false.
Both Assertion(A) and Reason(R) are correct as explained below:
When the light at the inner surface of the water drop gets internally reflected if the angle between the refracted ray and normal to the drop surface is greater than the critical angle, then a rainbow is formed.
