To put it simply. We group our EM waves into groups such as X-rays, microwaves, visible light etc. I was wondering, if the properties of say, x-rays, slowly change into the properties of say, gamma rays, or as soon as the wavelength is larger than 10 picometers it's properties become that of an x...
An oft cited problem with the planetary model of hydrogen is that, if the electron were in fact classically orbiting the proton, then it would radiate away all of its energy and fall into the nucleus.
The quantum mechanical approach fixes this by saying that there exist states for the electron ...
Without invoking Hermitian conjugation (which, to my mind at least, would beg the question), what is it that makes the bra $\langle\psi\rvert$ the unique dual of the ket $\rvert\psi\rangle$?
For instance I know that provided $\rvert\psi\rangle$ is not null then $\langle\psi\rvert$ maps $\rvert\...
The our Universe consist of about 22% Dark Matter (DM). Such matter is a main stuff of galaxies. Also, Black Holes (BH) lives in galaxies. We know, DM sujected to gravitational interaction. So, BH should absorb DM, and increase it event horizon. Comparing such process with Hawking radiation, ...
Keeping it simple, what is the physics approach to a current in a wire connected to a battery? How does the electric field behaves? I've read somewhere that, contrary to the common conception, electrons don't really flow as water in a hose so, what is really going on there? How is energy transpor...
