A ray of light strikes a glass plate at ...

A ray of light strikes a glass plate at an angle `60^@` . If the reflected and refracted rays are perpendicular to each other, the refractive index of the glass is,

A

`sqrt3`

B

`(3)/(2)`

C

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

D

2

Text Solution

Verified by Experts

The correct Answer is:
A
Angle of refraction `r =60^(@)` , Angle of incident i - `30^(@)` sin i = `nxxsinr`
`n=(sin30^(@))/(sin60^(@))=sqrt3`
