Polarization
A water wave is a 3 dimensional thing. dimension 1: amplitude. Dimension 2: wavelength. dimension 3: the crest & trough. If a water wave were two dimensional we would not see it. When a water wave is viewed we see lines proceeding at right angles to the amplitude and the wavelength. The crest of the wave is at right angles to it's amplitude and wavelength. how would you polarize a water wave? Perhaps the magnetic component is the same as a water waves crest and trough component. So many aspects of reality are ignored. When I look at a web page about water waves it shows me a cross section of the water wave and it even talks about the crest and trough as mearly the high and low point of the wave but what I really mean by crest and trough is the line that an artist would draw when depicting a wave. Maybe the ridge of the wave is a better term. Ridge and valley are its 3rd ...
