A light ray falls on the air glass interface at an angle of `30^(@)`. What is the angle of refraction for this rays ? `(n_(ag)=(3)/(2))`.

Text Solution

Verified by Experts

Given `n_(ag)=(3)/(2),anglei=30^(@)`
`n_(ag)=(sini)/(sinr)implies(3)/(2)=(sin30^(@))/(sinr)`
`implies sinr=(sin30^(@))/(3//2)=(1//2)/(3//2)=(1)/(3)implies r=19^(@)3.`.
