(1) The work function of a particular metal is 2.00 eV. (a) If the metal is illuminated with monochromatic light of wavelength 550 nm, what will be the maximum kinetic energy of the emmited electrons and, (b) their maximum speed? (c) What is the required stopping potential? (d) What are the threshold frequency and corresponding wavelength for the metal? (2) A potential difference of 40kV is applied across an X-rays radiated? please I need help..and need the answer by this coming monday,29th november 2004!!!!
