A metal surface in an evacuated tube is illuminated with monochromatic light causing the emission of photoelectrcss which are collected at an adjacent electrode. For a giwen intensity of light, the way in which the photocurrent I depends in the potential difference Vbetween the electrodes is shown by approximate graph in Fig. If the experiment were repeated with light of twice the intensity but the same wavelength, which of the graphs below would best represent the new relation between I and VI (In these graphs, the result of the original experiment is indicated by a broken line.)
  • a)
  • b)
  • c)
  • d)
Correct answer is option 'B'. Can you explain this answer?

Intensity of incident light is directly proportional to the number of photoelectrons emitted from the metal surface. So, greater the number of photoelectrons emitted, greater will be the photoelectric current for the same frequency of incident light.
