The minimum frequency of light needed to eject electrons from a metal is called the threshold frequency, 0 . Find the minimum energy needed to eject electrons from a metal with a threshold frequency of 4.17×1014 s−1. E0= J With what maximum kinetic energy will electrons be ejected when this metal is exposed to light with a wavelength of 245 nm? KEelectron= J
