Acertain minimum energy, , is required to eject an electron from a photosensitive surface. any energy absorbed beyond this minimum gives kinetic energy to the ejected electron. when 510.-nm light falls on a cesium surface, an electron is ejected with a kinetic energy of 8.85×10-20 j. when the wavelength is 430. nm, the kinetic energy is 1.61×10-19 j. a calculate for cesium, in joules.
