Relativistic Energy and Momentum

According to classical physics, time flow is the same for every observer. But according to einstein's theory, time flow is different for different observers. The idea that time flow is not the same for all may sound strange because we may not experience this effect in everyday life. This effect is only observed when an object moves with some velocity comparable to the velocity of light. This velocity is termed relativistic velocity.

Question

Learning Goal:
To understand how to find the wavelength and
diffraction patterns of electrons.
An electron beam is incident on a single slit of width
a. The electron beam was generated using a
potential difference of magnitude V. After passing
through the slit, the diffracted electrons are
collected on a screen that is a distance L away
from the slit. Assume that V is small enough so
that the electrons are nonrelativistic. Ultimately, you
will find the width of the central maximum for the
diffraction pattern.
Part A
In any diffraction problem, the wavelength of the waves is important. To find the wavelength of
electrons, you can use the de Broglie relation λ =, but you first must find the momentum of one
of the electrons. The electrons are accelerated through a potential difference V. Use this
information to find the momentum p of the electrons.
Express your answer in terms of the mass of an electron me, the magnitude of the charge on
an electron e, and V.
