Question

A ray of light is incident on the surface of a glass plate at an
angle of incidence equal to Brewster’s angel Φ. If m represents
the refractive index of glass with respect to air, then the angle
between the reflected and the refracted rays is
(a) 90° + Φ (b) sin⁻¹(μ cos Φ)
(c) 90º (d) 90º-sin⁻¹ ( sinΦ/μ)

Answer 1

Explanation:

When, the incidence angle of ray is equal to Brewster's angle then angle between reflected & refracted ray is 90o (i.e. π/2)
