Question

Prove with an activity how angle of reflection is equal to angle of incident.​

Answer 1

Answer

whenever a ray of light i.e. the incident will hit a point at plane mirror i.e. the normal then the ray of light will get reflected back in the same way i.e. the reflected ray. both rays form an angle on the normal i.e. the angle of incidence and angle of reflection. now as the angles formed, the imaginary line, i.e the normal, is a right angle i.e 90 degrees and both the angles of incidence and reflection respectively get divided into two 45 degrees angles respectively. hence it is proved that the angle of incidence = angle of reflection.
