The stopping potential for photoelectrons from a metal surface is V_(1) when monochromatic light of frequency upsilon_(1) is incident on it. The stopping potential becomes V_(2) when monochromatic light of another frequency is incident on the same metal surface. If h be the Planck’s constant and e be the charge of an electron, then the frequency of light in the second case is:
