    In a photoelectric effect experiment , photons of energy 5 eV are incident on metal surface . They liberate electrons which are just stopped by an electrode at a potential of 3.5 V with respect to metal . The work function of the metal surface in eV is :

    Statement 1: Though light of a single frequency (monochromatic light) is incident on a metal, the kinetic energies of emitted photoelectrons are not equal. Statement 2: The energy of electrons just after they absorb photons incident on metal surface may be lost in collision with other atoms in the metal before the electron is ejected out of the metal.

    When yellow light is incident on a surface , no electrons are emitted while green light can emit. If red light is incident on the surface , then

    Monochromatic light incident on a metal surface emits electrons with kinetic energies ranging from 0 to 2.5 eV. What is the least energy of the incident photon, if for removing the tightly bound electron from the metal surface an energy of 4.3 eV is required ?
