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

`sqrt3/sqrt2`

B

`sqrt2/sqrt3`

C

`1/sqrt2`

D

`sqrt2`

Text Solution

Verified by Experts

The correct Answer is:
A
Here, angle of incidence = i = `60^@`
Angle of refraction = r = `45^@`
Refractive index of the medium B relative to medium A
`= n_(BA)= (sin i)/(sin r)=(sin 60^@)/(sin 45^@)`
`=(sqrt3/2)/((1/sqrt2))=sqrt3/sqrt2`
