When light of wavelength lambda is incident on a metal surface, stopping potential is found to be x. When light of wavelength nlambda is incident on the same metal surface, stopping potential is found to be (x)/(n+1) . Find the threshold wavelength of the metal.

(i) In the explanation of photoelectric effect we assume one photon of frequency with v collides with an electron and transfers its energy.This lead to the equation for the maximum energy E_(max) of the emitted electron as E_(max)=hv-phi_(0) Where phi_(0) is the work function of the metal If an electron absorbs 2 photon (each of frequency v)What will be the maximum energy for the emitted electron? (ii)Why is this fact (two photon absorption)not taken into consueration in our discussion of the stopping potential?
