(i) How does one explain the emission of electron from a photosensitive surface with te help of Einstein's photoelectric equation ? (ii) The work function of the following metals is given : Na = 2.75 eV, K = 2.3 eV, Mo = 4.17 eV and Ni = 5.15 eV . Which of these metals will not cause photoelectric emission for radiation of wavelength 3300 Å from a laser source placed 1 m aways from these metals ? What happens if the laser source is brought nearer and placed 50 cm away ?
