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

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

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
