My book says that the de broglie wavelength of an electron is h / momentum, or h / (mv).

I also have that E = hf = momentum

^{2}/(2m) = 1/2 mv

^{2}.

I know that for a photon the frequency is speed of light / wavelength.

I'm wondering why the frequency for an electron is not 1/ wavelength. Is there any equation relating f and lambda for a particle (electron)?

Thanks for any help.
