Question

The dlagram below shows a light ray striking and reflecting
AO is the incident ray and OB the reflected ray. The angle between the
Incident ray and the reflected ray is 120°.
What is the value of the angle of reflection?​

Answer 1

Answer:

Angle of incidence= Angle of reflection...

According. to question...

Angle of incidence+Angle of reflection=120°

2(Angle of reflection.)=120°

Angle of reflection= 60°

Explanation:

hope it helps...

Answer 2

Answer:

angle of reflection = angle of incidence

Explanation:

angle between incident ray and reflected ray is 120

so,/i+/r=120

2/_r=120

therefore angle of reflection =60
