As the intensity of incident light increases        [1999]
  • a)
    photoelectric current increases
  • b)
    K. E. of emitted photelectrons increases
  • c)
    photoelectric current decreases
  • d)
    K.E. of emitted photoelectrons decreases
Correct answer is option 'A'. Can you explain this answer?

K.E. of electrons emitted depends upon the
frequency of incident rays rather than the
intensity. While number of photo electrons
emitted depends upon intensity of radiation.

If the intensity of light of a given frequency is increased, then the number of photons striking the surface per second will increase in the same ratio. This increased number of photons strikes more electrons of metals and hence number of photoelectrons emitted through the surface increase and

hence photoelectric current increases.
