1I think this should be moved to physics.stackexchange.com because it involves the physics of mirror images. – 2012-12-07

2@Limitless: I think in mathematics we can get away with assuming that the angle of incidence equals the angle of reflection, without worrying particularly about the physical reasons why it is so. – 2012-12-07
