Question:

A beam of white light (400 - 700 m) is incident on a metal plate of which the work function is 1.62 eV.

b) Determine the shortest de Broglie wavelength of the photoelectrons emitted from the plate surface.

(this is a quantum mechanic question so KE=1/2mv^2 or KE=p^2/2m cannot be use. Therefore, = h/2mKE can not be use.)
