Consider the photoelectric effect. The minimum energy needed to remove an electron is known as the work function it is like ionization energy for an atom. Label the work function W. (a) Gain a formula for the maximum kinetic energy an electron possesses if it is kicked off the surface by an incoming photon of frequency 0. Explain what is the threshold frequency in terms of W? (b) The work function for cesium is 2.14 eV. Explain what is the longest wavelength that can eject an electron from cesium? c) Explain what are the maximum kinetic energy as well as the speed of electrons emitted when the metal is irradiated with light of 300 nm?
