WebLaws of Reflection Now, the laws of reflection are formulated as: The angle of incidence is always equal to the angle of reflection. Both the angle of incidence and the angle of reflection are measured from the normal line; θ i =θ reflection. The incident ray, the normal, and the reflected ray- all lie in the same plane. tactical visor clip-on
