Question

What is the angle of incidence if the total angle between the incidence ray and reflected ray is 70⁰​

Answer 1

35°

Step-by-step explanation:

By laws of reflection,

Angle of incidence = Angle of reflection

Angle between incident ray and reflected ray = 70°

Angle of incidence + Angle of reflection = 70°

Since,

Angle of incidence = Angle of reflection

Angle of incidence + Angle of incidence = 70°

2 Angle of incidence = 70°

Divide 2 on both sides,

Angle of incidence = 70° / 2

Angle of incidence = 35°
