Intensity of monochromatic UV light incident on photocathode of a photoelectric cell is increased. What is its effect on:
photocurrent?
Answer
Answer
AIThe photocurrent increases. A more intense beam has more photons per second, so more photoelectrons are emitted per second; the photocurrent is directly proportional to the intensity (at constant frequency).
