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

Statement I A metallic surface is irradiated by a monochromatic light of frequency v gt v_(0) ( the threhold frequency ). The maximum kinetic energy and the stopping potential are K_("max") and V_(0) respectively. If the frequency incident on the surface is doubled, both the K_("max") and V_(0) are also doubled. Statement II The maximum kinetic energy and the stopping potential of photoelectrons emitted from a surface are linearly dependent on the frequency of incident light.

The stopping potential in an experiment on photoelectric effect is 2V. What is the maximum kinetic energy of the photoelectrons emitted ?

This question has statement - 1 and statement - 2 of the four choice given after the statements choose the one that best describes the two statements statement - 1 : A metallic surface is irradiated by a monochromatic light of frequency v gt v_(0) (the threshold frequency). The maxim,um kimetic energy and the stopping potential are K_(max) and V_(0) respectively if the frequency incident on the surface is doubled , both the K_(max) and V_(0) are also doubled statement - 2 : The maximum kinetic energy and the stopping potantial of photonelectron emitted from a surface are linearly dependent on the frequency of incident light

The stopping potential in an experiment on a photo electric effect is 1.5 V. What is the maximum kinetic energy of the photoelectrons emitted?
