FTP, name this experiment that confirmed the wave nature of the electron.
The detector employed, called a Faraday box, was mounted on arc so that it could be rotated to observe particles at different angles.  Those particles were accelerated from a heated filament with voltage, and the surprising result was interpreted with the Bragg law to give values for the lattice spacing in the nickel crystal.  As a result of it de Broglie's hypothesis was confirmed.  FTP, name this experiment that confirmed the wave nature of the electron.
