As I learned today in school, my teacher told me that when light enters a glass slab it slows down due to the change in density and it speeds up as it goes out of the glass slab. This causes a lateral shift and the light emerges out from the point different than that from where it should have act...
The correct interpretation is the first one. A hydrogen atom in a pure $d$ state, like, say, the $l=2$, $m_{L_z}=0$ state, really does point in a specific direction (i.e. the quantization axis).
There is nothing wrong with anisotropy, and particularly, there is nothing wrong with the existence o...
The notes given to me claim that the intensity of electric current depends on the intensity of radiation flashed on the metal. Why is it so?

Why is the saturation current the same, as you vary the frequency of incident light but keep its intensity constant?
If intensity is a measure of the energy of the incident beam, the product of the number of packets of light and the energy of each pa...
I imagined a theoretical experiment about gravity. First of all, I know that it is very hard to build such test tool with our current technology but it is just theoretical experiment to enlighten the general relativity.
Let's imagine, We have a big perfect sphere balloon whose inner side of t...
My dad once told me that he read an article about some physicists wanting to shoot neutrons (or protons) through earth as a way of communication. The explanation to why it would work being that at the atomar level theres mostly just "free space", so it would't hit anything.
This seems highly unl...
