Work function of aluminium is 4.2 eV.If two photons, each of energy 2.5 eV, are incident on it surface, will the emission of electrons take place? Justify your answer.

The work function of aluminium is 4.2 eV . If two photons , each of energy 3.5 eV strike an electron of aluminium , then emission of electrons will be

The work function of copper is 4.0 eV. If two photons, each of energy 2.5 eV strike with some electrons of copper, will the emission be possible?

The work function of a metal is 6 eV. If two pho tons each having energy 4eV strike with the metal surface. will the emission be possible?

The energy required to remove an electron from an aluminium surface is 4.2 eV. If two photons, each of energy 3.0 eV, strike an electron of aluminium, the emission of photoelectrons will

Two photons, each of energy 2.5 eV are simultaneously incident on the metal surface. If the work function of the metal is 4.5 eV, then from the surface of metal
