Assertion : Critical angle is minimum for violet colour.
Reason: Because critical angle

\theta_c=\sin ^{-1}\left(\frac{1}{\mu}\right)

and

\mu \propto \frac{1}{\lambda}

View answer and explanation

Correct option: A

If both Assertion and Reason are true and the Reason is a correct explanation of the Assertion

Option A is correct because both the Assertion and Reason are true, and the Reason correctly explains why the critical angle is minimum for violet color due to its higher refractive index.
