A ray of light strikes a plane mirror at an angle of 55° to the normal. What is the angle of reflection? What is the angle between the incident ray and the reflected ray?
The angle of reflection is
Angle of reflection is measured between the incident ray and the angle which it makes with the normal at the point where incident ray strikes the mirror surface.
Further on reflection, it makes the same angle i.e. angle of reflection is equal to angle of reflection.
Hence, as angle of incidence is
