Answer to Problem 1P

Option (c)

Explanation of Solution

Given:

The angle between the incoming ray and the reflected ray is 70° .

Formula used:

The angle of incidence = Angle of reflection. Therefore, The angle of reflection can be obtained by:

  r=θ2

Here, θ is the angle between incoming ray and the reflected ray.

Calculation:

The angle of reflection is calculated as

  r=θ2=70°2=35°

Conclusion:

Therefore, the correct option is (c).
