If we go on increasing the wavelength of light incident on a metal surface, what change in the number of electrons and the energy take place?

By increasing the intensity of incident light on the surface of a metal

The wavelength of light which is incident on a metal surface charge from lamda/2 " to " lamda/3 . The change is stopping potential will be

What happens to the energy of the photon incidenting on metal surface?

Light of wavelength lambda is incident on metal surface. Work function of metal is very small compare to kinetic energy of photon. If light of wave length lambda' is incident on metal surface then linear momentum of electron becomes 1.5 of initial, find out lambda' .
