What is the angle of incidence?

The angle of incidence is a term from the field of physics that studies light, and more specifically, the reflection of light.
Everywhere we are surrounded by reflective surfaces – mirrors, puddles, windows of houses and more. Surfaces have different reflective properties, but the rays of light that hit them behave the same way.
A ray falling on a surface is reflected at the same angle at which it hit it. In other words, the angle of incidence is equal to the angle of reflection. The angle of incidence is the angle between the falling lus and the perpendicular to the surface on which it falls. The angle of reflection, respectively, is the angle between the reflected beam and the perpendicular to the surface from which it is reflected.
