(a) Explain why XRD (X-Ray Diffraction) and TEM (Transmission Electron Microscopy) techniques are suitable in examining the unit cells and crystal structures of solids. (b) Calculate the expected diffraction angle (θ) for the first order reflection from the (310) planes of BCC chromium (Cr) when a monochromatic X-ray radiation of wavelength (λ) 0.757 Ao is used.

A Transmission Electron Microscope (TEM) is a kind of electron microscope that images by detecting electrons that pass through a sample (hence, the tranmission). This requires both very thin samples and much higher electron kinetic energies, at least an order of magnitude greater than a conventional Scanning Electron Microscope (SEM). If a particular TEM operates with an accelerating voltage of 150 kV, and therefore electrons with kinetic energies of 150 keV (recall KE = q∆V ), calculate the theoretical smallest...
