Question

A number of electrons are accelerated from rest through a
potential difference *V*. They are then incident on a double
slit setup with slit spacing *d*=74.4nm. The *m*=672
order maximum for this pattern is observed at *θ*=14.6∘ from
the normal to the slits.

1. What is the wavelength of the electrons?

2. What is the momentum of this electron?

3. Making the approximation that relativistic effects are
negligible, what is potential difference, *V*, through which
the electrons were accelerated?

d. If protons are used instead of electrons,...

Electrons are accelerated through a potential difference of 100V
and then shot through a slit of width 100 nm. They diffract and
form a pattern on a screen 0.5 m distant from the slit. How far
apart are the two dark spots on either side of the bright central
spot in the pattern?

For electron microscope which accelerates electrons from rest
through a potential difference of 10 kV.
(a) If the potential energy of an electron is taken to be 0
initially (at a 0 V plate), what potential energy does it have in
Joules after accelerating to the 10 kV plate? (The electrons
actually pass through a small hole in this plate before continuing
on toward the sample).
