Why wave theory of light could not explain the photoelectric effect ? State two reasons. Draw graph between frequency `nu` vs stopping potential `V_0` .

Choose the correct option for the graph between the frequency of incident light and the stopping potential.

The emission of electrons from a metal surface exposed rto light radaition of appropriate wavelength is called photoelectroic effect .The emmited electron are called photo=-weklectron work function of threshold energy may be defined as the minimum amount of energy required to ejercted electron from a most surface .According to Einstein Maximum kinetic energy of ejected electron = Aborbed energy - Work function (1)/(2) mv_(max)^(2) = h(v) - h(v_(n)) = hv [(1)/(lambda) - (1)/(lambda_(n))] Where v_(n) and lambda_(0) are thereshold frequency and threshold wavelength respectively Sopping potential : it is the miximum potential at which the photoelectric current becomes zero if V_(0) is the stopping potential eV_(0) = h(v- v_(0)) In the photoelectric currect effect the shape of strainght line graph between stopping potential (V_(0)) and frequency of incident light (V) gves

In a photoelectric effect experiment. The slope of the graph between the stopping potential and the incident frequency will be
