The refractive index of material of a prism of angles `45^(@)`, `-45^(@)`, and `-90^(@)` is 1.5. The path of the ray of light incident normally on the hypotenuse side shown in

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
a.
`Sini_(c)=(1)/(1.5)=(2)/(3)`
`i_(c)=sin^(-10)((2)/(3))=sin^(-1)(0.6667)=41.8^(@)`
The angle of incidence of face AC is `45^(@)` which is clearly greater than `41-8^(@)` .
