1)How can I find the wavelength as a function of the kinetic energy i)for photons, ii)for electrons?(adsbygoogle = window.adsbygoogle || []).push({});

i)For photons.

I think that I found it. I used the relation: E^2=c^2*p^2+(mc^2)^2

The photon's rest mass is 0. So we get: E=c*p

p=E/c ---> p=h*v/c --->p=h/λ

Finally: λ=c*h/E

ii)For electrons.

I don't know what to do. Do I have to use the same equations?
