An electron is accelerated from rest through a
difference of potential V.
a) Show that the de Broglie wavelength, in unit of angstrom Å
(10-10 m), for a non-
relativistic electron accelerated through a small potential
difference is:
λ =12.27/(v)^1/2
b) Calculate λ if the electron is accelerated through 50 V.
c) Find the de Broglie wavelength for a relativistic electron that
is accelerated from rest
through a large difference potential difference at a modern
particle collider.
d) Show that
( λ non-relativistics − λ relativistics)/ λ relativistics = 2.21 ≈
2.2
for electrons with
total energy of 10 MeV. In other words, that the percent error
between the non-
relativistic and the relativistic de Broglie wavelength is about
220% for 10 MeV
electrons.

Show that the de Broglie wavelength of an electron accelerated from rest through potential difference of V volts is 1.226/squareroot V nm.
An electron has been accelerated from rest through a potential difference of 2.5 x 103 V. What is the de Broglie wavelength of the electron? Can someone show every step please not sure how to go about this question. I know de broglie is wavelength= h/mv but not sure what to do with the potential difference and get speed instead. thanks!
