Question

If the angle of incidence is zero degrees, what is the angle of reflection?

• A. 0
• B. 90
• C. 180
• D. 45

Answer 1

Answer: (A)

Step 1: Given that:

The angle of incidence($\angle i$) = $0^0$

Step 2: Calculation of angle of reflection:

1. The angle of incidence is the angle between the normal and the incident ray.

2. The angle between the reflected ray and the normal is called the angle of reflection.

3. According to the laws of reflection, the angle of incidence is equal to the angle of reflection.

That is;

Angle of incidence($\angle i$) = Angle of reflection($\angle r$)

Therefore,

The angle of reflection will be= $0^0$

Thus,

Option A) $0^0$ is the correct option.
