Question

What does de Broglie’s standing-wave argument explain about a hydrogen atom?

Options

• The electrical forces between electrons

• Its discrete orbits and energy levels

• The relative intensities of all its spectral lines

• The structure of every complex atom

Answer 1

The quantum condition obtained from standing waves is the basis for discrete orbits and energy levels in a hydrogen atom. It explains Bohr’s angular-momentum quantisation through the electron’s wave nature.
