Question

Which of the following statements about the photoelectric effect are true? The intensity of the light beam does not affect the photocurrent.The kinetic energies of the emitted electrons do not depend on the light intensity.A weak beam of light of frequency greater than the threshold frequency yields more current than an intense beam of light of frequency lower than the threshold frequency.For light of a given frequency the kinetic energy of emitted electrons increases as the value of the work function decreases. Group of answer choices I, III, IV All are true I, II, IV II, III, IV
