What does the law of reflection mean?

La ley de reflexión establece que el ángulo que forma el rayo incidente con la normal, es igual al ángulo que se forma entre el rayo reflejado y la normal

The law of reflection states that the incident ray, the reflected ray, and the normal to the surface of the mirror all lie in the same plane. Furthermore, the angle of reflection is equal to the angle of incidence.

Explanation:

The three laws of reflection are:

1. The angle between the incident ray and the normal is equal to the angle between the reflected ray and the normal

2. The incident ray, the normal and the reflected ray are all in the same plane

3. Incident ray and refracted ray are on different sides of the normal
