In the photoelectric experiment, the frequency of the incident radiation is doubled. What will be its effect on the photoelectric current?

Options

  1. APhotoelectric current will not change.
  2. BPhotoelectric current will be doubled
  3. CPhotoelectric current will be halved
  4. DPhotoelectric current will become zero

Correct answer

A. Photoelectric current will not change.

Step-by-step solution

The photoelectric current in a photoelectric effect experiment depends on the intensity of the incident radiation, which corresponds to the number of photons incident per unit time per unit area. The frequency of the incident radiation determines the energy of each individual photon, given by E = h . Increasing the frequency of the incident radiation increases the kinetic energy of the emitted photoelectrons, provided the frequency remains above the threshold frequency. However, the number of photoelectrons emitted
