Photoelectric current does not depend on energy of the radiation, but on its intensity . Explain. |
| Answer» Solution :According to Elinstein, a single incident photon can eject only a single electron PROVIDED that if it has sufficient ENERGY. As the INTENSITY of the incident radiation increases, the number of incident photons and HENCE the number of ejected electrons increases. As a result photoelectric current increases. On the other hand above threshold frequency, the energy of hte incident radiation has no EFFECT on the number of photoelectrons ejected. | |
