# A ray of light traveling in air strikes a flat, horizontal plane mirror such that the incident ray makes an angle of \(30^\circ\) with the surface of the mirror. Which of the following correctly states the angle of reflection measured relative to the normal, and compares it to the angle of incidence?

A ray of light traveling in air strikes a flat, horizontal plane mirror such that the incident ray makes an angle of \(30^\circ\) with the surface of the mirror. Which of the following correctly states the angle of reflection measured relative to the normal, and compares it to the angle of incidence?

![A diagram depicting a horizontal flat surface representing a plane mirror. A vertical dashed line representing the normal is drawn perpendicular to the mirror surface at point P. An incident light ray arrow comes from the upper left, pointing toward point P on the mirror surface. The angle between the incident ray and the horizontal mirror surface is labeled 30^\circ. The angle between the incident ray and the vertical normal line is unlabeled. No reflected ray is drawn. No other lines, labels, or text appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1785826312-GxKr3f.jpg)

- **A.** The angle of reflection is \(60^\circ\), and it is equal to the angle of incidence.
- **B.** The angle of reflection is \(30^\circ\), and it is equal to the angle of incidence.
- **C.** The angle of reflection is \(60^\circ\), and it is greater than the angle of incidence.
- **D.** The angle of reflection is \(30^\circ\), and it is less than the angle of incidence.
