A ray of light is incident on a glass plate of refractive index 1.5. The angle between the reflected and refracted rays is `90^(@)`. What is the ratio of wavelenth of reflected to refracted rays?

A

2.1

B

1.5

C

1.6

D

1.7

Text Solution

Verified by Experts

The correct Answer is:

B

`mu_(g) = 1.5, (lambda_(a))/(lambda_(g)) = ?`
`mu_(S) = tan theta_(P) = (lambda_(a))/(lambda_(g)) = 1.5`
