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.

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.
