Answer: Regular reflection occurs when a parallel beam of light falls on a plane mirror band reflected as a parallel beam. They occur on polished surfaces. A diffuse reflection occurs on rough surfaces where a parallel beam of light is reflected in all directions. Laws of reflection. 1. The incident ray, the normal and the reflected ray at the point of incidence must be on the same plane.
