What happens when a ray of light falls normally (or perpendicularly) on the surface of a plane mirror?

As ray of light falls normally on mirror, this means that angle of incidence is 0°. From second law of reflection, we know that angle of incidence is equal to angle of reflection. So, angle of reflection will also be zero. Therefore, the light ray will be reflected back along the same path.
