Figure shows a ray of light as it travels from medium A to medium B. Refractive index of the medium B relative to medium A is

A

`(sqrt(3))/(2)`

B

`(sqrt(2))/(sqrt(3))`

C

`(1)/(sqrt(2))`

D

`sqrt(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
Given, angle or incidence, `i=60^(@)`, angle of refraction, `r=45^(@)`
Refractive index of the medium B relative to medium A,
`mu_(BA)=(sini)/(sinr)=(sin60^(@))/(sin45^(@))=((sqrt(3))/(2))/((1)/(sqrt(2)))=(sqrt(3))/(sqrt(2))`
