Ángulo de incidencia

The video tutorial explains the concept of light reflection, focusing on the angle of incidence and the law of reflection. It describes how a light beam reflects off a surface, forming an angle with a perpendicular line at the point of incidence. The law of reflection is introduced, stating that the angle of incidence is equal to the angle of reflection.

Explain the significance of the perpendicular line in reflection.

How is the angle of incidence related to the angle of reflection?
