The photeselestric effect is observed when light of a sufficiently high frequency is focused onto a polished metal surface, emitting photo electrons with a kinetic energy that is given by the difference betweent he photon enerzy and the work function of the metal historically, this effect was very confusing. for most wave phenon tand ight was wel known to behave as a wave phenomenon·ore nerease the increasing the amplitude of the wave. in the case of light, this means increase- there are simple more electrons emitted increasing the ententisty. however, with increased intensity, the kinetic energy of the photoelections emited does not albert einstein (1879-1955) offered a solution to this perplecing problem in hi 190s einen die erzeugung und verwandlung des lichtes betrefflenden heuristischen gesichtspunkr. einstein proposed the following relationship: kinetic- hw-e work function energy of an emitted photoelectron, hw is the energy of a photon of frequency v and ework function is the wrok function for the metal used in the ion is the energy required to remove an electron from the surface of the metal experiment. the work functi references einstein, albert (1905). the work function of cesium is 2.1 ev. what is this energy in? hint: 1 ev-1,602 x 10-19) annalen der physik 17(6 132-148 (1905) 34x 1019) 21x 1019 64x 1019 43x 1019 19, 0 19, 0
