I'd say that light rarely "gets polarized". In most cases, some polarizations are either absorbed or reflected away while others pass through.Wrichik Basu said:I would like to experiment before putting down any answer on such topics.
You are referring to my case of incident polarised light or the normal one?SlowThinker said:I'd say that light rarely "gets polarized". In most cases, some polarizations are either absorbed or reflected away while others pass through.
I agree. It sounds as if something 'forced' the random E vectors all to lay in a certain direction. "Polarisation" of an unpolarised beam involves selection of the E component of all the random vectors in a chosen direction.SlowThinker said:I'd say that light rarely "gets polarized".

Incident unpolarised light.sophiecentaur said:What "normal" one?
You seem to think there is something different about the Vertical components in a randomly polarised beam and the vertical components in a beam that has already passed through a polariser. You may need to re-think your ideas about what polarisation actually means.Wrichik Basu said:Incident unpolarised light.
Brewster's Law is a physics principle that describes the relationship between the angle of incidence and the angle of reflection for light that is polarized perpendicularly to the plane of incidence.
When vertically polarised light is incident on a medium, Brewster's Law states that the reflected light will be completely polarised, meaning that it will have a single direction of oscillation. This only occurs at a specific angle of incidence, known as the Brewster angle.
The formula for Brewster's Law is tan θB = n2/n1, where θB is the Brewster angle, n1 is the refractive index of the incident medium, and n2 is the refractive index of the medium the light is entering.
Brewster's Law is used in various practical applications, such as polarizing filters for cameras and sunglasses, and in optical devices such as polarizing microscopes and LCD screens.
If the angle of incidence is not at the Brewster angle for vertically polarised light, the reflected light will not be completely polarised. This means that the reflected light will have components in multiple directions of oscillation, resulting in a loss of contrast and clarity.
