Question

# A light ray strikes a plane mirror at an angle of $28^{\circ}$ to the normal. If the light source is moved so that the angle of incidence increases by $34^{\circ}$, what is the new angle of reflection?

In this problem, we have a plane mirror, and we need to find the angle of reflection. To solve this problem, we are going to use the law of reflection $\theta_{i}= \theta_{r}$ where $\theta_{i}$ is the angle of incidence, and $\theta_{r}$ is the angle of reflection. Also, the light source is moving, so we have to find the angle of incidence for that case.
