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.
Incident ray striking a plane mirror surface.
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?
