Question

If the angle between the incident ray and the reflected ray is ${70}^{\circ }$, what is the angle of incidence?

• A. ${90}^{\circ }$
• B. ${35}^{\circ }$
• C. ${45}^{\circ }$
• D. $0^{\circ }$

Answer 1

The correct option is B

${35}^{\circ }$

According to the law of reflection, the angle of incidence is equal to the angle of reflection.

Given that sum of the angle of incidence and the angle of reflection is ${70}^{\circ }$

Hence, each of the angles must be of ${35}^{\circ }$

So, the angle of incidence = ${35}^{\circ }$
