The purpose of this lab was to use the de Broglie relationship lambda = h/p to measure the spacing of the molecular lattice of a very thin carbon film. To do this a simple electron gun mounted in a vacuum tube is used to accelerate electrons to strike the carbon film. Electron diffraction pattern is then visible on the phosphorescent coated end of the tube. By de Broglie's relationship the electron beam will exhibit diffraction a predictable pattern.
There are a few difficulties with this lab. The most prominant
