Question

OR
If the angle between the plane mirror and the incident ray is 40° what are the angles of
incidence and reflection ?
(2)
If the angle between the mirror and reflected ray is 23° what is the angle of incidence of the​

Answer 1

angle with normal=90-40=50

so angle of incidence=angle of reflection=50 degree.

2) angle of incidence=angle of reflection=90-23=67degree

Answer 2

Answer:

incidence angle is made with incident ray so it is 40°and angle of reflection is always same as incidence angle in a plane mirror which is 40°

Step-by-step explanation:

the angle is also 23°
