Question

the angle between the incident ray and the corresponding reflected ray is 70 degree the angle between the incident ray and the reflecting surface will be​

Answer 1

Answer:

180°-70°=110°

110°/2=55°

So the answer is 55°.

Hope it helps.

Answer 2

Answer:

55°

Explanation:

The angle between incident ray and normal ray is equal to the angle between normal ray and reflected ray

Hence i = r

Here, i + r = 70 => i + i = 70

=> 2i = 70

=> i = 35°

Angle between incident ray and the reflecting surface will be​ = 90 - 35

= 55°
