Above this sentence is an image of the diagram and paragraph I have been reading about polarization via scattering.
Question: Light EM waves are transverse waves aka move perpendicular to the direction they are traveling. There can be no polarization in the scattered light parallel to the original ray because that would require the original ray to be a longitudinal wave. Can someone clarify why this is the case?
I was trying to relate the scattering of unpolarized light to how unscattered light behaves through two polarizers. From observation when the second polarizer is orthogonal to the first, then no polarized light can get through. Should these two phenomenons be observed as separate cases?
