Calculate the wavelength of a photon having the same momentum as an electron
moving at 1.0 106 m/s.
The answer is supposed to be 0.73 nm.
Ek = (m*v^2)/2
Ek = hf - W
p = E/c = hf/c = h/[tex]\lambda[/tex]
The Attempt at a Solution
I first found Ek using the kinetic energy formula, using the speed of the electron given in the question and the mass of the electron.
I can't quite figure out where to go next.
