Homework Statement
Through what potential difference should you accelerate an electron from rest, such that it's de Broglie wavelength will be 0.1 nm.
Homework Equations
E = hf
λf = c
The Attempt at a Solution
My Thinking was;
E = hf
E = hλ/c
E= 6.626e-34 * 1e-10/3e8
which turned out 2.21e-58 J, which I'm pretty sure is wrong.
Anyone with some ideas or a worked solution would be fantastic :D
Regards all,
Will.
