How are photoelectron spectroscopy graphs generated?0 ▲
Shoot light at something --> electrons of atoms will absorb light energy, jumping up into excited state --> then, they will jump back down to ground state, releasing the absorbed energy as light; how much energy this light carries (as exhibited by its wavelength and frequency), corresponds exactly to how much energy the electrons released by jumping back down to ground state. So, when graphed, we will see a chart of the wavelengths and frequencies at which this light was released; this corresponds to the energy levels of the electrons.
Also, the relevant equations:
E = h*nu (energy = Planck's constant * frequency)
c = lambda*nu (speed of light = wavelength * frequency)
