Homework Statement
A proton is accelerated from rest through a potential of 1kV. Find its de Broglie wavelength.
Homework Equations
[tex]\lambda=h/p[/tex]
The Attempt at a Solution
I tried to get p (momentum) by energy comparison:
e*1000=0.5*m*v^2
v=437 621.130 016 524 m/s
which doesn't makes sense... what am I doing wrong?
