I have recently found one exercise in an exercise book:
During the transition from the first excited state of a hydrogen atom into the ground state, photons with a wavelength of 121.5 nm are emitted. The lifetime of the excited state is 10 ns. Calculate the natural line broadening of the excited state using the energy uncertainty.
Could someone please explain to me briefly what the 'natural line broadening of the excited state' is?
