Question

tha refractive index of diamond is 2.419. Calculate tha critical angle for light going from diamond to air

Answer 1

Answer:

The critical angle is 24.45°.

Explanation:

Given that,

Refractive index of diamond = 2.418

Critical angle :

Critical angle is inversely function of sine.

In mathematically term,

$n=\dfrac{1}{\sin c}$

Where, n = refractive index

c = critical angle

We need to calculate the critical angle for light going from diamond to air

Using formula of critical angle

$\sin c=\dfrac{1}{n}$

$\sin c=\dfrac{1}{2.418}$

$c=\sin^{-1}0.414$

$c=24.45^{\circ}$

Hence, The critical angle is 24.45°.
