Question

When the incident ray strikes the mirror making an angle of 40 with the mirror, then the angle between incident ray and reflected ray is

Answer 1

Explanation:

if I understand correctly you are trying to ask the angle between the angle of incidence and angle of reflection.

so we have to find gamma.

now the question has given the angle of ray of light with the mirror so the angle of incidence will be 50 degrees which is equal to angle reflection

therefore, gamma equals to 260 degrees after
