How does the photoelectric current vary with the intensity of incident radiation?

Assertion: A photosensitive surface is illuminated by a monochromatic light of wavelength lambda and intensity I. The number of photoelectrons emitted per second is doubled when the intensity of light is doubled. However, the maximum speed of emitted electrons remains unchanged. Reason: The number of electrons emitted per second is directly proportional to the intensity of the incident light. The kinetic energy of the emitted photoelectrons is independent of the intensity of the light.

Assertion : Photoelectric effect demonstrates the wave nature of light. Reason: The number of photoelectrons is proportional to the frequency of light.

In photoelectric effect, the number of photoelectrons emitted is proportional to :
