Question

If the angle of incidence is ${70}^o$, then calculate the angle between the incidence ray and the reflected ray.

• A. ${40}^o$
• B. ${140}^o$
• C. ${130}^o$
• D. ${110}^o$

Answer 1

The correct option is B ${140}^o$

Given $\angle i={70}^o$
The angle between incident ray and the reflected ray $=2\angle i={140}^o$
