question mark

Suppose there is a metal containing electron whose work function is 3hv.Let light falls on the metal and suppose the electron get attacked by a photon particle of energy hv. So is there any chance whether the electron will release when another 2 such photon will strike the electron making the total energy=3hv. Means whether the electron will hold up the enrgy until it is attacked by another 2 photon particles of energy 2hv.

Dear Sudip, emission of é takes place only, when energy supplied to it exceeds it's work function. Here sum of energies of 3 photons is equal to 3hv, so energy of 1 photon is very less than 3hv,i.e. 1hv, so electron will not be emitted. Also it will hold up energy in form of heat surrounding it, until it is attacked by another 2 photons of energy 2hv.
