The Photoelectric current from a photosensitive metal, above the threshold frequency, depends on the :
- A frequency of the incident radiation
- B work function of the metal
- C intensity of the incident radiation
- D stopping potential
Answer & Solution
Correct Answer
(C) intensity of the incident radiation
Step-by-step Solution
Detailed explanation
The photoelectric current is directly proportional to the intensity of the incident radiation because intensity determines the number of photons striking the surface per second, which in turn determines the number of electrons ejected. C) intensity of the incident radiation
