Question: When the photon energy is less than the work function of the material the light is shone upon, how many photoelectrons are emitted?
Sentence: Assuming the frequency is high enough to cause the photoelectric effect, a rise in intensity of the light source causes more photoelectrons to be emitted with the same kinetic energy, rather than the same number of photoelectrons to be emitted with higher kinetic energy.
Answer in sentence: no
