Theory The law of reflection defines how incident light rays reflect off the surface of a conducting material, and is governed by the following principles: The incident ray, the reflected ray, and the normal to the surface at the point of incidence all lie in the same plane. The angle of reflection is equal to the angle of incidence. Derivation The reflected ray for normalized normal vector \(n\) and incidence vector \(i\) pointing towards the surface, is calculated as follows: \[r = i − 2 ...
