When a light ray is reflected from a wall, the angle of incidence is not equal to the angle of reflection.
The diagram in Fig. shows an incident ray AO and the reflected ray OB from a plane mirror. The angle AOB is 30°. Draw normal on the plane mirror at the point O and find :
Select the correct alternative
The angle between the incident ray and the ray reflected from the plane mirror is 70°. The angle of incidence will be :
