According to the law of reflection, how do the angles of incoming and reflected light compare?

The law of reflection states that when light reflects off a surface, the angle at which the incoming light strikes the surface (the angle of incidence) is equal to the angle at which the light reflects away from the surface (the angle of reflection). This principle holds true for all types of reflective surfaces, whether they are smooth mirrors or rough surfaces that scatter light.

Since both angles are measured from the same line perpendicular to the surface (which is known as the normal), their equality signifies that the behavior of light respects this foundational rule of optics. Therefore, the correct understanding is that the angles of incoming and reflected light are indeed equal to each other.
