Main Question or Discussion Point
I am just trying to wrap my mind around this. Einstein explained the effect using photons, but why couldn't the electron get stripped by a wave. I understand that the electron will not get stripped until the energy is high enough, but I dont understand why a wave could not be resonsible. It seems to make perfect sence that a low energy wave will just wiggle the electron, but never have enough amplitute to actually remove the electron from the shell. Also, since light contains an oscilating electric feild, doesn't it follow that it is that electric field that strips the electron? I just really dont understand what a photon is. I know it has the energy E=hf, but, take a radio wave for example, the energy is very low because f is very low, so the energy of the photon is very low... but would the photon also have the long length of the wave? The idea of photons seems to work with high energy light, but not the longer wavelengths.
