Question

a ray of light is incident on a plane surface of refractive index √3 at certain angle and its reflected and retracted rays are perpendicular to each other find the angle of incidence​

Answer 1

Answer:

ANSWER

Given

i+r+90

∘

=180

∘

i+r=90

∘

Where,

i= angle of incidence = angle of reflection

i= angle of refraction.

μ=
