In the photoelectric effect, electrons are ejected by matter only if they are given energy from light of a high enough frequency. It does not matter how bright the light source is; only frequency matters. Which reasoning explains why particles are better than waves for describing this phenomenon? a.) The energy from the waves of light coming from bright lights would add up and free an electron.
b.) The energy from photons of light should be enough to knock out an electron, no matter what the frequency of light is, because it is moving so fast.
c.) The energy from photons of light would never be enough to free electrons because they don't have the same energy if they are just particles.
d.) The energy from light waves is canceled out by interference at low energies, but not at high energies, so it can free electrons with bright light.
