since it is defined (from what i can tell) as h/p,(adsbygoogle = window.adsbygoogle || []).push({});

is it interchangeable with the classical wavelength in equations involving waves in general? or is it a special separate case for matter?

that is,

for photons we have the following equation:

E = hf

E = hc/λ

can the same equation be used to find the wavelength/energy of electrons?
