Question

If the angle between the incident ray and the reflected ray is ${70}^{\circ }$, what is the angle of incidence? [2 MARKS]

Answer 1

Explanation: 2 Marks

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

Given that sum of 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 = ${35}^{\circ }$
