A ray of light is incident on a transparent glass slab of refractive index `sqrt3`. If the reflected and refracted rays are mutually perpendicular, what is the angle of incidence?

Text Solution

Verified by Experts

According to Brewster's law
`mu tan i_(p)`
`:. Sqrt3 = tan i_(p) " " [ :' mu = sqrt3 " (given")]`
`rArr tan 60^(@) = tan i`
Hence angle of incident, `i = 60^(@)`
