Question 8 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: na = 2d0 B If electrons with wavelength (3.60x10^-12) m travel down and transmit through a thin Cu film sample with a lattice parameter of (4.8500x10^-10) m and the distance R between the transmitted and first order (111) spot is (6.872x10^-3) m, what is the camera length in meters?
