Write the relation between the work function (w) and threshold frequency (V_0) in photoelectric effect.

Photoelectric effect takes place in element A. Its work funcation is 2.5 eV and threshold wavelength is lambda . An other element B is having work function of 5 eV . Then find out the wavelength that can produce photoelectric effect in B.

Statement I: The stopping potential becomes double when the frequency of the incident radiation is doubled Statement II: Work function of the metal and the threshold frequency of photoelectric effect are proportional to each other.

Initially, energy of incident photon was double of the work function of metal in a photoelectric effect. Finally energy of incident photon made 10 times of the work function. The ratio of maximum possible speed of photo electrons in initial & final case is alpha/beta . Then find minimum value of alpha :

In ultraviolet light of wavelength 200 nm is used in an experiment of photoelectric effect with lithium cathode (w = 2.5 eV). Then calculate (i) K. E _(max) (ii) Stoppiong potential
