(a) Given the wavelength of visible light is from 380 to 730 nm and the work function of sodium is 2.28 eV,
(i) calculate the maximum kinetic energy of the photoelectron emitted from the surface.
(ii) sketch a graph of maximum kinetic energy, KEmax against visible light frequency, v for this experiment. Label the threshold frequency, vo.
(b) If the sodium target is replaced with another material with a lower work function, what will happen to your graph in part (a)(ii)? Explain your answer.
(c) Is photon and photoelectron equivalent? Explain your answer.
