Q. The relation for critical angle (C) is sin C =

क्रांतिक कोण (C) के लिए संबंध Sin C = है

A
n₁/n₂
B
n₂/n₁
C
n₂ × n₁
D
1/(n₁ + n₂)

Explanation

The critical angle CC is the angle of incidence in the denser medium (with refractive index n1n_1) for which the angle of refraction in the rarer medium (with refractive index n2n_2) is 90°. The formula is:

sin⁡C=n2n1\sin C = \frac{n_2}{n_1}

where n1>n2n_1 > n_2.
