In a photoelectric effect experiment
WebIn photoelectric effect we use low energy photon (generally IR, VISIBLE OR UV region)so photons are completely absorbed....if we use high energy photon some of it will penetrate and the phenomenon would be compton shift rather than photoelectric effect ( 7 votes) Upvote Flag Show more...

Figure 29.2. 2: An EM wave of frequency f is composed of photons, or individual quanta of EM radiation. The energy of each photon is E = h f, where h is Planck’s constant and f is the frequency of the EM radiation.
WebAug 21, 2015 · The experiment is severely limited by the fact that as soon as the photon energy exceeds the photoemission threshold of the collector electrode, measurements become very difficult, if not impossible, because light reflected from the sample generates a photoemission current from the collector.
