Q. The work function of a metal surface is 1.8 eV. Compute the threshold wavelength.
Work function W = hγo = h C / λ 0
λ 0 = h C / W
= 6.626 X 10-34 X 3 X 10 8 / 1.8 X 1.6 X 10 -19
= (19.878 / 2.88) X 10-7 m
= 6.902 X 10-7 m
Derivation
When a certain beam of light falls upon a metal surface, it ejects photoelectrons from it. The number of photoelectrons ejected per second by the beam of light depends upon on
