The variation of photoelectric current with collector potential for two different frequencies, \\\\(\
u_1>\
u_2\\\\) is shown in figure.The photoelectric equation in terms of stopping potential \\\\(V_0\\\\) is given by , \\\\(eV_0=h\
u-h\
u_o\\\\)So, \\\\(V_0 \\propto \
u\\\\) Thus, Stopping potential will be higher for \\\\(\
u_1\\\\).
