Question

Light strikes a mirror at an angle of incidence of 43.5 degrees. What is the angle of reflection?

Answer 1

The Law of Reflection states that the angle of incidence equals the angle of reflection:

$$\theta_i=\theta_r.$$

Therefore, $\theta_r=43.5^{\circ}.$

Answer:

$\theta_r=43.5^{\circ}$
