MCQ
The angle between an incident ray and the plane mirror is $30^\circ .$ The total angle between the incident ray and the reflected ray will be:
- ✓$30^\circ$
- B$60^\circ$
- C$90^\circ$
- D$120^\circ$
The angle between the incident ray and the mirror is $30$ degrees.
Angle of incidence = angle of reflection.
$90$ degrees is going directly into the mirror.
So, $90 – 30 = 60$ degrees.
The total angle between the incident ray and the reflected ray will be $120$ degree.
