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

Is this wavelength in vacuum? Answer; as per mass of CPH is constant, and Vc is for an alone CPH, so wavelength should be in vacuum, that there is not any gravity effect. But i
