Answer:
The number of photoelectrons are increased
Explanation:
According to Albert Einstein, when light falls on a clean metal surface, electrons are ejected from the clean metal surface. This is known as photo electric effect.
The kinetic energy of the emitted photoelectron depends on the energy of the incident photon and the work function of the metal. If the energy of the incident photon is less than the work function of the metal, photoelectric effect does not occur.
Below a given threshold frequency or wavelength called the threshold frequency or threshold wavelength photoelectric effect does not occur.
However, doubling the photon flux of light doubles the intensity of the light. This only leads to increase in the number of photons and have nothing to do with the energy of the emitted photoelectrons.
