Hey guys, assume that i performed and experiment to measure the maximum kinetic energy of electrons released due to the photoelectric effect due to light falling on a metal target (i.e. Sodium).
KE = hf - W (where W = work function, f = frequency and h = Planck constant)
since KE = 1/2 mv^2
i need to find the work function of this metal due to the photoelectric effect, do i assume the the velocity of the electron (or photon confused :S) is traveling at 3x10^8 (c) ??
p.s. i have all other known variables excluding W
thanks.
