A hollow prism made of transparent glass...

A hollow prism made of transparent glass is filled with a transparent liquid. The angle between the two refracting faces of the prism is `90^@`. If light incident on one of the faces at grazing angle comes out of the other also at a grazing angle, the refractive index of the liquid is

A

1.414

B

1.333

C

1.35

D

1.4

Text Solution

Verified by Experts

The correct Answer is:
A
Refractive index of prism,` mu =1/(sinC)`
`implies C= A/2=90^@/2=45`
`implies mu=1/(sin45^@)=1.414`
