Will table sugar twist polarized light?
I recently saw this awesome video by Steve Mould where he explained that a sugar solution in water will turn polarized light in the clockwise direction.
The explanation basically boils down to sugar molecules (glucose) having a handedness (they are…

Grid pattern on a car window when viewed through polarized sunglasses
When driving with polarized sunglasses I noticed that the rear window shows a grid pattern:
Interestingly, the pattern is much more visible when viewing a reflective surface, like another car. I also observed the same pattern on some other cars'…

How does the Ocean polarize light?
I know that the light gets polarized in the plane of the ocean, but why is that? It seems to me that the molecules are free to be in any position or location, so why is it that the 'vertical' polarization gets ignored?

Field of a Polarized Object
In Griffith's Electrodynamics, in the section 4.2, just after the equation 4.9, he writes "sleight-of-hand casts this integral into a much more illuminating form"...
I have a doubt in that. If the Gradient (or differentiation if carried out) is with…

Effect of temperature on optical rotation of sugar solution
How does temperature affect the specific optical rotation of sugar solution at constant concentration and why?
If, for example, the temperature is increased, will the optical rotation for a given path length and concentration increase or decrease,…

How to deduce dielectric function/permitivity of two dimensional material
In the enormously cited paper, Frank Stern [1] gave the fomula of dielectric function of two dimensional material. But the process remains very obscure to me.
The longitudinal electric field…

Why reflected light from a mirror don’t get absorbed in polarized sunglasses?
If i see a reflection on a horizontal surface and i try to cancel it out using my polarized sunglasses, then it cancels out much of that reflection. But when i put a small mirror inside that reflection on the same surface and try to cancel out the…

Does the inverse-square law apply to linearly polarized light?
It's a stupid question but: We did and experiment using linearly polarized microwave radiation generators and receivers. Our teacher asked to check experimentally if the receiver measurements are proportional to the intensity of the radiation I or…

Circular polarization: properties and detection
I am thinking about the property of circular polarization of light. I have two circularly polarized beams, one is rounding in positive direction, other is negative. My task is to figure out:
if those two polarized beams are circular (I can use…

about polarization of light
In the course of circuits and electronics, I remember there is an experiment to show the polarization of the wave as lissajous figures. I am wondering for polarized laser, is there any way to visualize the polarization in the similar way? I try to…

Can circular polarized light be cancelled?
I can cancel the light output from an LED screen by placing a linear polarizer at 90 degrees from the linear polarizer built into the LED display. OLED displays use circular polarizers instead of linear polarizers; in what way can I cancel the light…

Polarization of the Sky?
I was hiking and noticed as I tilted my sunglasses (which are probably polarized), right at the horizon where the sky was against a mountain, it would change from lighter to darker blue.
This only occured right above the horizon, and I didn't see a…

What sort of polarisation causes this effect
By some chance I acquired a pair of specialized '3d' glasses to be used in conjunction with a poster, such that when viewing the poster (which was a map of australia) the contours popped in and out of the page (seemingly). I was messing about and I…

How can I determine what degree of polarization my polarized film is?
I have a piece of either circular or linear polarized film that I had laying around, however, I have no knowledge of the degree of polarization that the film has. How can I test to see what the degree of polarization is. I have my monitor and other…

Creating certain polarisations from light source
I'm thinking about this situation:
Two plane polarized beams of light of equal intensity with polarizations that are mutually orthogonal are produced from a gas discharge lamp emitting nearly monochromatically at mean wavenumber ν and with bandwidth…
