My physics class is currently studying the photoelectric effect, and I was wondering if anyone could clarify this for me:
"Only photons of a high-enough frequency, (above a certain threshold value) could knock an electron free. For example, photons of blue light had sufficient energy to free an electron from the metal, but photons of red light did not. More intense light above the threshold frequency could release more electrons, but no amount of light below the threshold frequency could release an electron."
What is it about the more intense light that gives it the capability to release more electrons?
