How does the angle of incidence change as you rotate the red ray counter clockwise? Ofcourse at the point where the incident ray is horizontal and travelling the parent focal length, the angle of incident and reflection are 0. So does the angle of incidence and reflection decrease equal as they reach the horizontal direction? | |
