WebPhotoelectric Effect the diffracted light is greater on one side than on the other. Turn on the mercury lamp and let it warm up. The lamp should be left on at all times during the experiment since it needs a warm-up time and a cool down time before it will come back on. 2. Use a card or piece of paper to observe the mercury lines from the ... The photons of a light beam have a characteristic energy, called photon energy, which is proportional to the frequency of the light. In the photoemission process, when an electron within some material absorbs the energy of a photon and acquires more energy than its binding energy, it is likely to be ejected. If the photon energy is too low, the electron is unable to escape the material. Since a…
