In a photoelectric experiment , it both the intensity and frequency of the incident light are double , then the saturation photoelectric current :
A
Remains constant
B
Is halved
C
Is doubled
D
Becomes four times
Answer
Is doubled
Explanation
Solution
: The saturation photoelectric current is directly proportional to the intensity of intensity of incident radiation but it is independent of its frequency, therefore the saturation photoelectric current becomes doubled. When both intensity and frequency of the incident light are doubled
