The frequency and intensity of a light source are both doubled. Consider the following statements
A. The saturation photocurrent remains almost the same
B. The maximum kinetic energy of the photoelectrons is double

Options

A. Both (I) and (II) are correct
B. Both (I) and (II) are incorrect
C. Only (I) is incorrect
D. None of the above

Answer

B

Explanation

The saturation photocurrent (i) depends on intensity (l) of light i.e., `I prop l.`
So, when intensity changes, the saturation current also changes. Hence, the statement (l) false.
The maximum kinetic energy depends upon the frequency of light. So , the kinetic energy is doubled when frequency is doubled.
Hence , option (b) is false
