Question

Critical angle of light passing from glass to air is minimum for

Moderate

A

Red
B

Green
C

Yellow
D

Violet

Solution

$_{a} μ_{g} = \frac{1}{\sin C} \Rightarrow \sin C = \frac{1}{{aμ}_{g}}$
As $μ$ for violet colour is maximum, so sin C is minimum and hence critical angle C is minimum for voilet colour.
