Which of the following increases the maximum kinetic energy of the photoelectrons emitted?

Which of the following increases the maximum kinetic energy of the photoelectrons emitted? Correct Answer Increasing the frequency of the incident beam

The maximum kinetic energy of the photoelectrons can be increased by increasing the frequency of the incident beam and at the same time keeping the number of incident photons fixed. Now, this would result in a proportionate increase in energy, and in this way, the maximum kinetic energy can be increased.
