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 away from these metals?
What happens if the laser source is brought nearer and placed 50 cm away?
pls help in this que
