FirstInTest · Accepted Answer

Let's analyze each statement regarding the photoelectric effect:
**A. The saturation current is constant with collector plate potential for different frequencies of incident radiation.** This statement is correct. The saturation current depends on the number of photoelectrons emitted per unit time, which is directly proportional to the intensity of incident light, not its frequency (above the threshold frequency). If the intensity of incident radiation is kept constant, the saturation current will be the same regardless of the frequency of the light.
**C. The saturation current is different with collector plate potential for different intensity of incident radiation.** This statement is correct. A higher intensity of incident light means more photons strike the metal surface per unit time, leading to the emission of a greater number of photoelectrons per unit time. This directly results in a higher saturation current.
**E. Below threshold frequency no photo electrons are emitted.** This statement is correct. The threshold frequency is the minimum frequency of incident light required to cause photoelectric emission. If the frequency of the incident light is below this threshold, no photoelectrons will be emitted, no matter how high the intensity of the light.
Statements B and D are incorrect as they contradict the established principles of the photoelectric effect regarding the dependence of saturation current on frequency and intensity.
