Suppose that we do not know quantum mechanics and that the electron of a hydrogen atom behaves like a harmonic oscillator with a certain oscillation frequency f. In this model, an excited electron can therefore emit light and this has the same frequency f as the oscillating motion of the electron.It is observed that the light emitted by such an atom has a frequency of 800 Hz and the oscillating movement of the electron has an amplitude of 0,418 nm. In m / s, what is the modulus of the maximum speed of the electron?
