Why reflection causes polarisation of light

AI Thread Summary
Reflection causes the polarization of light due to the interaction of light waves with a reflective surface, where certain orientations of light waves are preferentially absorbed or reflected. When light reflects at a specific angle, known as Brewster's angle, the reflected light becomes completely plane polarized. This occurs because the electric field vectors of the light waves aligned with the surface are more likely to be absorbed, while those perpendicular to the surface are reflected. Phase differential refers to the difference in phase between the light waves that are reflected and those that are refracted, contributing to the polarization effect. Understanding these concepts is crucial for applications in optics and photography.

Hello all

I know that polarisation of light can occur from reflection, and when the reflected ray is 90degrees from the refracted ray the relfected light is 100% plane polarised.
So, my question is why is it that reflection causes polarisation of light?

Thanks

because the light on the vertical plane were annihilated through phase differential.
 
Ok, and what is phase differential?

Thread 'A quartet of epi-illumination methods'

Well, it took almost 20 years (!!!), but I finally obtained a set of epi-phase microscope objectives (Zeiss). The principles of epi-phase contrast is nearly identical to transillumination phase contrast, but the phase ring is a 1/8 wave retarder rather than a 1/4 wave retarder (because with epi-illumination, the light passes through the ring twice). This method was popular only for a very short period of time before epi-DIC (differential interference contrast) became widely available. So...

Thread 'Effective absorption coefficient of gold nanoparticles'

I am currently undertaking a research internship where I am modelling the heating of silicon wafers with a 515 nm femtosecond laser. In order to increase the absorption of the laser into the oxide layer on top of the wafer it was suggested we use gold nanoparticles. I was tasked with modelling the optical properties of a 5nm gold nanoparticle, in particular the absorption cross section, using COMSOL Multiphysics. My model seems to be getting correct values for the absorption coefficient and...

Thread 'The focal length of the eye and image inversion'

After my surgery this year, gas remained in my eye for a while. The light air bubbles appeared to sink to the bottom, and I realized that the brain was processing the information to invert the up/down/left/right image transferred to the retina. I have a question about optics and ophthalmology. Does the inversion of the image transferred to the retina depend on the position of the intraocular focal point of the lens of the eye? For example, in people with farsightedness, the focal point is...
