Blackbody Radiation and Planck`s Hypothesis of Quantized Energy
... This is even true if we have a particle beam so weak that only one particle is present at a time – we still see the diffraction pattern produced by constructive and destructive interference. Also, as the diffraction pattern builds, we cannot predict where any particular particle will land, although ...

Hence each absorption of photon by the atom transfers a discrete amount of energy by hn only. If hn is not enough to provide sufficient energy to overcome the required work function, W0, no phot ...
