Question

When light is incident perpendicular to the surface. what will be the angle of reflection?

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

Answer 1

The correct option is B $0^o$

When a ray of light is incident perpendicularly on a reflecting surface, it is incident along the normal ray.

So, angle of incidence is $0^0$

As angle of reflection $=$ angle of incidence, the angle of reflection is equal to $0^0$.
