There are a lot of questions about this topic on this site, none of them answer my question specifically.
I have read this question:
What does a photon emitted by an atom "look" like?
I think of the emitted photon as a point particle (but with a polarization vector) traveling in a straight line ...
Let's assume we are in a perfect vacuum and let a photon travel from a point $A$ to a point $B$. As far as my understanding of quantum physics goes, the photon takes all possible paths between $A$ and $B$, as shown in this picture:
Here, I have drawn 3 possible paths $a$, $b$ and $c$. Path $a$ g...
So we can derive this expression by equating force of attraction on the electron by the nucleus to the centripetal force acting on the electron, i.e: $$ \frac{KZe^2}{r^2}= \frac{mv^2}{r},$$ where $m$ is the mass and $e$ is the charge on the electron, $Z$ is atomic no. of the $H$-like particle, $K...
