The work function for photoelectric effect

In an experiment on photoelectric effect the frequency f of the incident light is plotted against the stopping potential V_(0) . The work function of the photoelectric surface is given by ( e is the electronic charge)

Discuss the photoelectric effect. Mention the condition for the photoelectric effect.

Work function of metal in photoelectric effect is 3.5 eV for -1.2 V potential photoelectric current become zero,Hence…….

Threshold frequency for photoelectric effect from a metal surface of work function 4.5 eV is

Threshold frequency for photoelectric effect on sodium corresponds to wavelength 5000 overset@A Its work function is

Define work function of metal and photoelectric effect.
