What is the angle of reflection when a ray of light is incident normally on a plane mirror?

The angle of reflection when a ray of light is incident normally on a plane mirror will be zero degree because the angle of incidence will be zero degree as the ray is incident normally. By law of reflection, angle of incidence= angle of reflection.
