The following diagram shows an incident ray AO and the normal ON on a plane mirror. Find the angle of incidence and angle of reflection.
Define the following term
Reflected ray
Two mirrors A and B are placed at right angles to each other as shown in the following figure.
A ray of light incident on mirror A at an angle of 25° falls on mirror B after reflection. The angle of reflection for the ray reflected from mirror B would be
How many times is a ray of light reflected by two plane mirrors placed parallel and facing each other?
Draw figure showing the position of the plane mirror. Also, label the angle of incidence and angle of reflection on it.
Angle of incidence is greater than the angle of reflection.
Assertion (A): A ray incident along normal to the mirror retraces its path.
Reason (R): In reflection, the angle of incidence is always equal to the angle of reflection.
