The repetitions of the lines form the sequence, the refraction of the lines in polarization angles is generated through repetitions of the lines and divisions of the Brewster angles, but the light here is not emitted from a single point of reference, the light and shadow is a result of the accumulation of lines in a point of polar refraction, where the oscillators indicate the object its changes, the repeated triangles are images of the first reflection, those with larger numbers are successive reflections.
