One of the concept questions asked whether increasing the intensity of light waves would make able to eject an electron. Just wanted to clarify if "increasing the intensity" meant increasing the amount of the same-sized light waves hitting the surface, or if it meant increasing its frequency, thereby making it able to eject an electron.
I agree with Miranda-- I think that increasing intensity meant increasing the number of photons, not the frequency since it was a concept question looking to test whether students recognized the significance of the photoelectric experiments.
