Dual Nature of Radiation and Matter

  1. As the intensity of incident light increases
    1. photoelectric current increases
    2. K. E. of emitted photo electrons increases
    3. photoelectric current decreases
    4. K.E. of emitted photo electrons decreases
Correct Option: A

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.
