Homework Statement
In quantum mechanics the de Broglie wavelength of an object depends
on its momentum according to λ=h/p where h is Planck's constant.
Protons of charge e and mass m are accelerated from rest through a
potential V. What is their de Broglie wavelength?
A) [itex]2h/\sqrt{}meV[/itex]
B) [itex]h/\sqrt{}2meV[/itex]
C) h[itex]\sqrt{}meV[/itex]
D) [itex]h/eV[/itex]
Homework Equations
