9. When light falls on a plane mirror, the beam gets​

Answer 1

Answer:

Regular reflection of light occurs from smooth surfaces like that of a plane mirror or highly polished metal surfaces. For example: When a parallel beam of light falls on the smooth surface of a plane mirror, it is reflected as a parallel beam in only one direction.Images are formed by regular reflection of light.

Answer 2

Answer:

When a ray of light falls normally (or perpendicularly) on the surface of a plane mirror, it gets reflected along the same path because the angles of incidence and reflection are both equal to zero. Thus, a plane mirror produces regular reflection of light. Since the angle of incidence and the angle of reflection are the same or equal, a beam of parallel rays falling on a smooth surface is reflected as a beam of parallel light rays in one direction only.
