Question
Define the following when reflection takes place from the surface of a plane mirror :normal

Answer

When a ray of light falls normally on the surface of a plane mirror, the incident ray is reflected back along the same path. This is because the angle of incidence is zero, so the angle of reflection will also be zero.
