Yes, if we allow raditions of a fixed frequency to fall on plate and the accelerating potential difference between two electrodes is kept fixed then the number of photoelectrons emitted per second is proportional to the intensity of incident radition.

Effect of frequency- The maximum kinetic energy of the photoelectrons increases linearly with the frequency of the incident radition, but independent of its intensity.

If the frequency of incident radition is less than the threshold frequency then no photoelectrons emission is possible, howsoever large is the intensity of incident radition.
