In a photoelectric effect experiment a light of frequency 1.5 times the threshold frequency is made to fall on the surface of photosensitive material. Now if the frequency is halved and intensity is doubled, the number of photoelectrons emitted will be:
  • a)
    Doubled
  • b)
    Quadrupled
  • c)
    Zero
  • d)
    Halved
Correct answer is option 'C'. Can you explain this answer?

Since  i.e. the incident frequency is less than threshold frequency. Hence there will be no emission of photoelectrons.
⇒ current = 0
