    Physics -- deriving Planck's constant

    hello, im trying to do this homework, where i have to derive Plancks constant using an experiment where we used some LED lights of different wavelengths to work out voltage at different wavelengths. From that i worked out the frequency and ekmax of the electrons given out. however i have no...
