if your light is polarized perpendicular to the glass surface then there is no change in polarization.

Yes. Actually photons exert pressure on any surfaces exposed to them. For example, photons emitted by the Sun exert pressure of $9.08 \mu N/m^2$ on the Earth. Reference: https://en.wikipedia.org/wiki/Radiation_pressure

Yes - you can even propel spaceships with it - Solar Sail Although Solar radiation pressure at the Earth is around 9E-6N/m2 while the thrust from a Saturn V rocket is 34 MN, so you would need a solar sail something like 2000Km on a side to get the same acceleration

Just think about it a little in terms of light rays and reflecting surfaces (mirrors). The light rays from the right hand of the driver behind you are reflected by the mirror to reach your eyes on the right of the light rays from his left hand, so you see them that way. Likewise for his head and torso. But if you look straight at him, his right hand appears ...

Nothing in the universe is continuous. Matter and light are made up of particles, and physicists have strong reason to believe that even space is quantised. As for the mirror, photons travel from the lightsource to the object. There they are either absorbed or reflected, depending on their wavelength and the properties of the object at the point of ...

The approximate number of photons which strike a mirror and enter your eye over the period of a couple seconds is a massive quantity (in Mathematica): << PhysicalConstants` Convert[(1 Milli Joule 600 Nano Meter)/(PlanckConstant SpeedOfLight), 1] Output: 3.02047*10^15 Since this is in the quadrillions, for all practical intents and purposes, ...

A Mirror flips the image front to back, not left to right. In the mirror your nose is in front of your face, but in reality it should be behind your face. Because your image is flipped front-to back it just so happens to appear from our common sense perspective that left and right are actually flipped. The L-R flip is an illusion symptomatic of the front to ...

You are right. Rainbows can occur all over the sky. However the traditional one and two internal reflections of the primary and secondary bows send light back towards the sun and hence their bows appear opposite the sun and centered on the antisolar point. The reflection of the main light makes these bows stand out. And only the light that enters a droplet ...

Check this: You can see that the angle difference is much bigger when the light gets reflected, and can be differentiated much easier. Also another factor which probably plays a very important role is that the sun is in front of you, and its simply too strong in comparison with the light from the droplet, thus making it even more difficult to inspect this ...

Since Community in its wisdom brought this up again, lets make things clear: 1.Suppose if we have the planning of home to be made in the same manner of the circle shaped fibre with same material as that of quartz. We can have same light circulating all over once incident. So, if this happens we can have light through out the house with out light being ...

Assuming 3D RealD glasses - uses circular polarized light to cancel images. To understand better, ask yourself why do I see my eyes when both eyes are opened? The answer is that your brain mixes two reflected images: one image contains your left lens blacked the other image contains the right lens blacked When you close an eye, you cancel one image. ...
