Notably used for communication with submarines, so in particular crucial as part of sending an attack signal to that branch of the nuclear triad.

merlijn.sebrechts.be/blog/2020-08-02-why-one-snap-store/ has some very good comments on how snap is more closed than Flatpak.

Snap's permission system is extremely annoying, notably restricting access to home files. They need a popup that says "permission required by app, accept?" urgently!!!

Split in energy levels due to interaction between electron up or down spin and the electron orbitals.

Numerically explained by the Dirac equation when solving it for the hydrogen atom, and it is one of the main triumphs of the theory.

This is likely the easiest one to produce as the frequencies are lower, which is why it was discovered first. TODO original setup.

Also because it is transparent to brick and glass, (though not metal) it becomes good for telecommunication.

Some notable subranges:

Ah, shame, they are a bit weak.
