Why Does Reflected Light Get Polarized But Transmitted Light Does Not?

AI Thread Summary
Reflected light can become polarized due to the Brewster angle, where the p-component is fully transmitted and the s-component is partially reflected, resulting in s-polarization. Transmitted light retains both polarization states, but the amount of s-polarization decreases because some is reflected. The confusion arises from the understanding that while reflected light can achieve plane polarization, transmitted light does not become fully polarized. The discussion clarifies that transmitted light maintains a mix of polarization states, influenced by the reflection process. Understanding these principles is essential for grasping the concepts of polarization in optics.

confusion about polarization...

i have been confusing according this picture which is taken from http://hyperphysics.phy-astr.gsu.edu/Hbase/hframe.html" .

Confusion is "i studied that is when the reflect light perpendicular to transmitted light then two ways become plane polarize".but here reflection part get the plane polarization .but transmitted wave does not get any polarize.

please help me . I'm very beginner for this subject...

Are you talking about "Polarization by Reflection" http://hyperphysics.phy-astr.gsu.edu/Hbase/phyopt/polar.html#c1 ?

The pictures shows light incident at the Brewster angle. This is the angle at which the p-component of light is 100% transmitted. Thus the only component that is reflected is the s-component, hence s-polarization of reflection.

Note that the s-component is only partially reflected, so that the transmitted light still has the two polarization states. However, assuming no absorption, the transmitted light will have the same amount of p-polarization as the incident light but less in the case of s-polarization since part of it is reflected.
 
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...
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...
