Question

The refracting angle of prism is 1/2° and its refractive index is 1.5 for yellow colour. Deviation of yellow colour passing through it is

Answer 1

refracting angle of prism is 1/2 °.

did you get “ refracting angle of prism ” ?

angle made by two refracting surface of the prism is known as refracting angle of prism. it is simply called angle of prism.

so, angle of prism, A = 1/2°

refractive index of yellow colour, $\mu_y$ = 1.5

so, deviation of yellow colour is $\delta=(\mu_y-1)A$

= (1.5 - 1) × 1/2°

= 0.5 × 1/2°

= 1/4°

hence, deviation of yellow colour passing through prism is 1/4°

Answer 2

Answer:

1/4 degree

Explanation:

uy =1-1.5=0.5

0.5/1/2=1/4
