The law of reflection is illustrated in Figure \(\PageIndex{1}\), which also shows how the angles are measured relative to the perpendicular to the surface at the point where the light ray strikes. We expect to see reflections from smooth surfaces, but Figure \(\PageIndex{2}\) illustrates how a rough surface reflects light.

The law of reflection is illustrated in Figure 1.5, which also shows how the angle of incidence and angle of reflection are measured relative to the perpendicular to the surface at the point where the light ray strikes.
Law of Reflection: The law of reflection states that the angle of reflection equals the angle of incidence: θr = θi. The angles are measured relative to the perpendicular to the surface at the point where the ray strikes the surface.

If a ray of light could be observed approaching and reflecting off of a flat mirror, then the behavior of the light as it reflects would follow a predictable law known as the law of reflection. The diagram below illustrates the law of reflection.
We have already discussed the laws of reflection and refraction in Chapters 26 and 33 of Volume I. Here’s what we found out there: The angle of reflection is equal to the angle of incidence. With the angles defined as shown in Fig. 33-1 , \begin {equation} \label {Eq:II:33:1} \theta_r=\theta_i. \end {equation}
Ley de la Reflexión. Un rayo de luz incidiendo sobre una superficie reflexiva, se reflejará con un ángulo igual al ángulo de incidencia. Ambos ángulos se miden con respecto a la normal a la superficie. Esta ley de la reflexión se pueden derivar del principio de Fermat.
