Confusion regarding the selection rule in hydrogen atom
When you describe your state as $3 D_{5/2}$ you are assuming so-called LS coupling. In that case, the actual selection rule for $J$ (a quantum number resulting from the coupling between electron's spi …

Linewidth of the Caesium clock
The energy difference between every two atomic levels is a well-defined value, as those levels represent distinctive quantum states. So there is no problem with a statement that those two hyperfine le …

Why don't we get infinite energy from a continous emission spectrum?
You should think about the energy spectrum (which is your emission spectrum times photon energy in the function of frequency/wavelength) like a density function. Then if you want to specify the energy …
