KCET · Physics · Dual Nature of Matter
In a photo electric experiment, if both the intensity and frequency of the incident light are doubled, then the saturation photoelectric current
- A is halved
- B is doubled
- C becomes four times
- D remains constant
Answer & Solution
Correct Answer
(B) is doubled
Step-by-step Solution
Detailed explanation
In photoelectric effect, saturation photocurrent is directly proportional to the intensity of incident radiation but independent of frequency of incident radiation. Hence, saturation current in photoelectric effect becomes double when both intensity and frequency of the incident light are doubled.
