Question

if a ray strikes perpendicularly on the plane mirror, at what angle it will get reflected?​

Answer 1

Answer:

Large telescopes use reflection to form an image of stars and other astronomical objects. Figure 1. The law of reflection states that the angle of reflection equals the angle of incidence—θr = θi. The angles are measured relative to the perpendicular to the surface at the point where the ray strikes the surface.
