Question :
A ray falls on the surface of plane mirror and makes an angle of 44° with it. what is the angle of incidence and reflection.
Concept :
● Angle of incidence is always measured from the normal to the mirror.
● Angle of incidence = angle of reflection
Solution :
Since the incident rays makes 44° with the mirror.
Angle of incidence = 90 - 44
Angle of incidence = 46°
Angle of incidence = 56°
We know that
Angle of incidence = Angle of reflection
Angle of reflection = 46°
Angle of reflection = 46°
