Given below are two statements:Statement I : Out of microwaves, infrared rays and ultraviolet rays, ultraviolet rays are the most effective for the emission of electrons from a metallic surface.Statement II : Above the threshold frequency, the maximum kinetic energy of photoelectrons is inversely proportional to the frequency of the incident light.In the light of above statements, choose the correct answer from the options given below

Select the incorrect statement regarding photoelectric effectThe number of ejected electrons do not depends upon the frequency of light.The kinetic energy of ejected electrons depends upon the frequency of the light usedThe number of the ejected electrons is proportional to the intensity of the light usedThere is a time lag between the striking of light and ejection of electrons

Light of wavelength 390 nm is directed at a metal electrode. To find the energy of electrons ejected, an opposing potential difference is established between it and another electrode. The current of photoelectrons from one to the other is stopped completely when the potential difference is 1.10 V. Determine i) the work function of the metal and ii) the maximum wavelength of light that can eject electrons from this metal. (amplify the signal?)
