In a photoelectric experiment, if the intensity of incident light is doubled and the frequency is kept slightly greater than threshold frequency, then the saturation photoelectric current
Options:
Answer:
C
Solution:
In the photoelectric effect, the saturation photoelectric current is directly proportional to the intensity of the incident light, provided the frequency of the incident light is greater than the threshold frequency.
When the intensity of the incident light is doubled, the number of photons striking the metal surface per unit time is doubled. This results in the emission of twice the number of photoelectrons per unit time.
Therefore, the saturation photoelectric current is doubled.
Answer: is doubled
