Question

In TEM, we can obtain a diffraction pattern of a thin sample through the use of
objective apertures that act as a barrier for incoming electron radiation in the
microscope column. Due to the small angle that the beam makes as it transmits
through the crystal planes of TEM samples, the Bragg condition can be modified to:
ηλ 2d0
=
Determine the wavelength of electrons travelling through an objective aperture if
the diffraction spot produced satisfies the Bragg condition at (1.20x10^-2) (0 in
radians) for the first order (110) plane with a lattice parameter of (6.010x10^-10),
and the camera length between the CCD camera and sample is {c}.
