A beam of ligth having frequency `v` is incident on an initially neutral metal or work function `phi(hv gt phi)`. Then

A parallel beam of monochromatic radiation of cross-section area A(lt pi a^(2)) , intensity I and frequency v is incident on a solid conducting sphere of work function phi_(0)[hv gt phi_(0)] and radius 'a' . The sphere is grounded by a conducting wire. Assume that for each incident photon one photoelectron is ejected. Just after this radiation is incident on initially unchanged sphere, the current through the conducting wire is:

A when a photon of energy hv is incidnet on an electron in a metal of work function phi ( lt hv) , the electron will not necesserily come out of the metal . R : work function is the minimum energy required to liberate an electron out of a metal . So some electons may require more energy for their liberation .

When light of frequency v_(1) is incident on a metal with work function W (where hv_(1) gt W ) the photocurrent falls to zero at a stopping potential of V_(1) . If the frequency of light is increased to v_(2) , the stopping potential changes to V_(2) . Therefore the charge of an electron is given by

A beam of light of wavelength lambda is incident on a metal having work function phi and placed on a metal having work function phi and placed in a magnetic field B. The most energetic electrons emitted perpendicular to the field are bent in circular arcs of radius R. Then

When light of frequency v_1 incident on a metal with work function W_0 (where hv_1 gt W_0), the photocurrent falls to zero at a stopping potential of V_1. If the frequency of light is increased to v_2, the stopping potential changes to V_2. Therefore, the charge of an electron is given by
