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

Angle of refraction `r=60^@` , Angle of incident `i=30^@`
sini = n x sin r
`n=(sin 30^@)/(sin 60^@)=sqrt3`
