When radiation of frequency less than threshold frequency falls on a surface of metal, it gives energy to the electron and at a instant later another radiation of same frequency strikes the same electron, if the energy of two photon equals or is greater than the work function of the electron in that metal, does the electron get out of the metal surface?
What will happen if those two photon strike the electron at the same time.
