Electron diffraction patterns from a crystal can be used to determine the crystal lattice struct

Name: Electron diffraction patterns from a crystal can be used to determine the crystal lattice structure. In order to create clear electron diffraction patterns, incident electrons should have de Broglie wavelength comparable to the distance between adjacent atoms in the crystal, typically about 0.1 nm. What is the kinetic energy of the incident electrons required?

Step 1: Use the de Broglie wavelength formula: λ = h / p, where λ = 0.1 nm = 1 x 10^-10 m, h = P
