The correct Answer is:
To solve the question regarding the photocurrent in the photoelectric effect, we can break down the concepts step by step. ### Step-by-Step Solution: 1. **Understanding Photocurrent**: - Photocurrent is the electric current that results from the emission of electrons when light (photons) strikes a material, typically a metal. 2. **Effect of Intensity**: - The intensity of light refers to the number of photons striking the surface per unit time. - When the intensity of the incident photons increases, more photons are available to interact with the electrons in the material. - This leads to the emission of more electrons from the surface, resulting in an increase in the photocurrent. 3. **Effect of Frequency**: - The frequency of the incident light affects the energy of the photons (E = hf, where h is Planck's constant and f is the frequency). - Increasing the frequency does not increase the number of emitted electrons; rather, it affects the maximum kinetic energy of the emitted electrons. - If the frequency is below a certain threshold (the work function of the material), no electrons will be emitted, regardless of the intensity. 4. **Conclusion on Photocurrent**: - Photocurrent is directly proportional to the intensity of the incident light but is independent of the frequency of the light. - Therefore, the correct statement regarding photocurrent in the photoelectric effect is that it depends on the intensity of the incident light and not on its frequency. 5. **Choosing the Correct Option**: - Based on the analysis, the correct option is that photocurrent depends on the intensity of the incident light and does not depend on its frequency. ### Final Answer: The photocurrent in the photoelectric effect depends on the intensity of the incident light but is independent of its frequency. ---

In an experiment on photoelectric effect light of wavelength 400 nm is incident on a metal plate at rate of 5W. The potential of the collector plate is made sufficiently positive with respect to emitter so that the current reaches the saturation value. Assuming that on the average one out of every 10^6 photons is able to eject a photoelectron, find the photocurrent in the circuit.
