Final answer:
Regular reflection of light occurs from a plane mirror.
Step-by-step explanation:
When light reflects off a plane mirror, it undergoes regular reflection.
Regular reflection occurs when light waves strike a smooth surface and bounce off in a predictable manner. In the case of a plane mirror, the angle of incidence (the angle between the incident light ray and the normal to the plane mirror) is equal to the angle of reflection (the angle between the reflected light ray and the normal).
For example, if a light ray strikes a plane mirror at a 30-degree angle, it will reflect off at a 30-degree angle on the other side of the normal.
