Our knowledge regarding the structure of light is not clear, and the transition from particle model to wave model appears not to be really finished. All particle-based ideas are not swept out, and this fact causes the wave or particle paradox. This fact is demonstrated in the idea that aligning an optical system means fixation of light motion along an optical axis. This conclusion is infected by particle based thinking. When we instead strict follow the wave model we can conclude that only wave fronts are real. Therefore, aligning instead means that wave fronts orientations are fixed to be orthogonal to the optical axis. This orientation is defined by the normal to the wave fronts. This normal defines the ray concept, that is relevant in relation to reflectors and refractors, since these objects are transparent in relation to the ether wind. The ray is a mathematical tool without physical existence. The ray describes the physical reality of the wave fronts. So, when we use the law of reflection in a mirror, we must use wave front normal – and not real light motion.
