Question
Chemistry Question on Dual nature of radiation and matter
In a photoelectric experiment, if both the intensity and frequency of the incident light are doubled, then the saturation photoelectric current
A
remains constant
B
is halved
C
is doubled
D
becomes four times
Answer
is doubled
Explanation
Solution
The number of photoelectrons emitted, ie, photoeiectric current is independent of the frequency of the incident light and depends only upon its intensity.
Thus, the saturation photoeiectric current is doubled.
