when UV light is shone upon a metal, can electrons be ejected from the metal or does this only occur if there is another force in play (eg a potential difference to sweep the elctrons away)
also, if electrons (at their base energy level) only accept a specific frequency of UV light (which varies from element to element) [<correct me if i wrong here], then how come when you increase the frequency of UV light on a surface, we observe an increase in an emitted electrons total energy (ie, the electrons still absorbed the the EM radiation)
