Problem
A metal with threshold frequency 5.0×1014AHz is successively exposed to two monochromatic beams A and B of equal intensity having frequencies 6.0×1014AHz and 8.0×1014AHz respectively.
(i) Which beam produces the larger stopping potential?
(ii) Arrange beams A and B in order of the maximum kinetic energy of the emitted electrons.
