Wave-Particle Duality De Broglie Hypothesis: Any moving particle has an associated wave nature (1924). E k =hf true for electrons and all matter This means that light is not the only weird thing, all matter is weird De Broglie's Hypothesis tested in 1927 by Cliffton Davisson and Lester Germer of Bell Laboratories. They document electron diffraction

Nobel Prize De Broglie won in 1929 for his work Davisson and Germer won in 1937 for their work

The Impact De Broglie's hypothesis meant it was possible to predict the behavior of matter (including subatomic particles) using wave equations

The Impact De Broglie's hypothesis meant it was possible to predict the behavior of matter (including subatomic particles) using wave equations This idea was crucial for the development of quantum mechanics

Werner Heisenberg Electrons interact with photons because they have similar wavelengths.

Werner Heisenberg Electrons interact with photons because they have similar wavelengths. Photons are used to detect electrons Because of the relationship, any attempt to find the velocity and position of an electron causes those quantities to change (the Heisenberg uncertainty principle)‏

Quantum Mechanics Based on the work of de Broglie, Heisenberg, Schrödinger, Born, Einstein and others All matter behaves with both particle and wave nature

Quantum Mechanics Based on the work of de Broglie, Heisenberg, Schrödinger, Born, Einstein and others All matter behaves with both particle and wave nature The smaller a particle is, the more closely its behavior approaches a wave
