Find the maximum angle of refraction when a light ray is refracted from glass `(mu= 1.50)` to air.

Text Solution

Verified by Experts

Maximum angle of refraction from denser medium to rarer medium is the critical angle. Hence,
`1.5 sin C =1 sin 90^(@)`, where C = critical angle.
`sin C = 2//3`
`C = sin^(-1)2//3`
