Question

What is the angle between the incident and reflected rays when a ray of light is incident normally on a plane mirror?

• A. ${90}^o$
• B. ${45}^o$
• C. ${180}^o$
• D. $0^o$

Answer 1

The correct option is D $0^o$

When an incident ray strikes normally to any reflecting surface then the reflected ray will trace back the incident ray.

Hence angle between incident ray and reflected ray is $0^0$.
