The frequency and intensity of a light source are doubled. Consider the following statements
I. Saturation photocurrent remains almost the same.
II. Maximum kinetic energy of the photoelectrons is doubled.
I. Saturation photocurrent remains almost the same.
II. Maximum kinetic energy of the photoelectrons is doubled.
View answer and explanation
Correct option: C
I is false but II is true.
Option C (I is false but II is true) is correct because saturation photocurrent depends on intensity, and maximum kinetic energy depends on frequency.
