The photocurrent increases with increasing intensity of light.

Vedclass · Answer

(C) According to the experimental observations of the photoelectric effect,the photoelectric current is directly proportional to the intensity of the incident light,provided the frequency of the light is above the threshold frequency. $1$. The frequency of light determines the kinetic energy of the emitted photoelectrons,not the number of electrons (current). $2$. The photocurrent saturates at a certain voltage,so it is not directly proportional to the applied voltage for all values. $3$. The stopping potential depends on the frequency of the incident light,not its intensity. Therefore,the correct statement is that the photocurrent increases with increasing intensity of light.
