Explanation:
Photocurrent and Intensity of Light:
- The correct statement is that the photocurrent increases with increasing intensity of light.
- When light falls on a photocell, it generates electron-hole pairs, leading to the flow of current.
- Higher intensity of light means more photons are hitting the photocell, resulting in more electron-hole pairs being generated, thus increasing the photocurrent.
Stopping Potential and Intensity of Light:
- The stopping potential does not increase with increasing intensity of incident light.
- The stopping potential is the minimum potential that must be applied to stop the flow of electrons in a photocell.
- It depends on the energy of the incident photons, not on their intensity.
Photocurrent and Applied Voltage:
- The photocurrent is not directly proportional to the applied voltage.
- The photocurrent depends on the intensity of light and the characteristics of the photocell, not just the applied voltage.
Current and Frequency of Light:
- The current in a photocell does not necessarily increase with increasing frequency of light.
- The current depends on the number of electron-hole pairs generated, which is related to the intensity of light rather than its frequency.
Therefore, the correct statement is that the photocurrent increases with increasing intensity of light.
