Question

The refracted index of water is 1.33 calculate it's critical angle

Answer 1

$\bold{ \large{ \underline{ \underline{ \: Answer : \: \: \: }}}}$

$\to$ Critical angle = 48.590 Degrees

$\large \bold{ \underline{ \underline{ \: Explanation \: : \: \: \: }}}$

$\to$ Refractive index = 1.33

The Relation between Critical Angle (C) and Refractive index (R.I) is :

$\large \bold{ \fbox{ \fbox{R.I = \frac{ \: 1 \: \: } { \: \: sin \: C \: \: } }}}$

$\to$ 1.33 = 1 / sin C

$\to$ sin C = 0.75

$\to$ C = 48.590 Degrees

$\therefore$ Critical angle is 48.590 Degrees
