Question

what is the angle of deviation for a ray which is incident with an angle 45⁰ on the plane mirror​

Answer 1

Answer:

A ray of light strikes a plane mirror at an angle of incidence 45∘C as shown in fig. After reflection, the ray passes through a prism of refractive index 1.5 whose apex angle is 4∘. If the mirror is rotated by X degrees then the total deviation of ray becomes 90∘C.
