The reflection from plane mirror is shown in the diagram.

<h3><u>Explanation</u>:</h3>

The mirror is a plane surface which can reflect light. The diagram attached shows the schematic representation of reflection that occurs in a plane mirror.

The laws of reflection states that the incident ray, reflected ray and the normal at the point of incidence lies at the same plane. Here we can also see that all are lying on a same plane.

The second law states that angle of incidence is equal to angle of reflection. Here we can also see that the i =r. It is applicable here too.
