Homework Statement
I'm not even sure the problem is about matterwave:
A particle of mass m and charge e is accelerated by a potential difference V. Find the wavelength of the particle. Show that this result agrees with the classical one when the non relativistic limit is taken.
Homework Equations
Not sure, but I think that [tex]\lambda _B=\frac{h}{mv}[/tex] where m is the relativistic mass, i.e. [tex]m=\gamma m_0[/tex].
Maybe [tex]F=qE[/tex]?
The Attempt at a Solution
I'm not really sure how to find the motion equation of the particle and I need its velocity in order to calculate its de Broglie's wavelength. F=qE.
[tex]\Delta V =\int _A^b \vec E d \vec l[/tex]... I don't go anywhere that way.
I've no idea what I'm missing.
