Question

determine the refractive index of benzene if the criticle angle of it is 42 degree

Answer 1

Explanation:

Given: the critical angle is 42

∘

To find the refractive index of benzene

Solution:

Let the critical angle be C and refractive index be μ.

According to Snell’s Law,

C=sin-1 (1/u)

42° = sin-1 (1/u)

sin (42) = 1/u

u = 1/ 0.67

u= 1.49

1.49 is the required refractive index of benzene

Answer 2

Answer:

Explanation:

given critical angle c=42 degrees

we know, refractive index = 1/sin(c) = 1.49
