• (Diffraction)

Reflection

The incident ray, the reflected ray and the normal to the

reflection surface at the point of the incidence lie in the

same plane.

The angle which the incident ray makes with the normal is

equal to the angle which the reflected ray makes to the

same normal.

The reflected ray and the incident ray are on the opposite

sides of the normal.
