Question

If the reflected ray makes an angle of 60° with the normal, what angle must the incident ray make with the normal?

Answer 1

Find (243)^2/5 ÷ (32)^-2/5

Answer 2

By the snells, law the reflected ray is equals to the incident ray. So the angle of the incident ray is 60 degree.

Incident ray is the ray which strikes a media.

Reflected ray is the ray which is reflected after incidence.

By the snells law angle i=angle r.

Normal is a imaginary line separating the incident and the reflected ray.
