E) The emission spectrum of the hydrogen atom

Question

Quizplus · Accepted Answer

Electron diffraction by a crystal directly supports de Broglie's hypothesis by demonstrating that electrons can exhibit wave-like behavior, such as interference patterns, when they pass through a crystal lattice, which acts similarly to a diffraction grating for light waves. This experimentally confirms de Broglie's proposal that matter (like electrons) has wave properties.
