When a monochromatic ray of light is passed through an equilatorial glass prism , it is found that the refracted ray in glass is parallel to the base of the prism . If `i` and e denote the angles of incidence and emergence respectively then

A

`igt e`

B

`ilte`

C

`i=e`

D

`i+e = 90^(@)`

Text Solution

Verified by Experts

The correct Answer is:
C
The refracted ray is parallel to the base . This happens when the incident ray suffers minimum deviation . In this case `i= e`
