Question

If the angle between incident ray and normal is ${30}^o$.what will be the angle of incidence?

• A. ${60}^o$
• B. ${30}^o$
• C. ${90}^o$
• D. ${150}^o$

Answer 1

The correct option is B ${30}^o$

The angle between incident ray and normal ray is called angle of incidence.

Thus, $\text{The angle of incidence}={30}^o$
