7.4 Quantum Mechanics
Physicists were both mystified and intrigued by Bohr’s
theory. They questioned why the energies of hydrogen
electron are quantized, or, why is the electron in a Bohr
atom restricted or orbiting the nucleus at certain fixed
distance?
For a decade there is no logical explanation. In 1924, Louis
de Broglie provided the solution for this puzzle. If light wave
can behave like a stream of particles (photon) then, perhaps
particles such as electron can possessed wave properties.
De Broglie reasoning led to the conclusion that waves can
behave like particles and can exhibit wavelike properties.
