Question

prism with angle 60 , if the deviation angle is 16 , calculate the refractive index of the prism

Answer 1

Answer:

1.26

Explanation:

d=(u-1)A

A=60,u=16

16=60(u-1)

by solving

u=1.26

Answer 2

The refractive index of the prism is μ = 1.232

- It is given that :

Angle of prism, A = 60°

Angle of deviation, δ = 16°

- We know that refractive index of the prism is given by:

μ = sin (A+δ)/2 / (sin A/2)

μ = sin (60+16)/2 / (sin 60/2)

μ = sin (76/2) / sin 30

μ = sin 38 / sin 30

μ = 0.616 / 0.5

μ = 1.232
