De’ Broglie’s hypothesis and the birth of quantum mechanics
Electromagnetic waves (photons) have both particle and wave properties
D’Broglie proposed that all particles in the Universe could present this dualism:
- each entity in the Universe exhibits both particle and wave properties
Wavelength associated to the particles:
(h: Planck’s constant, m: mass, v: speed)
electrons in atoms have also wave properties
electrons form standing waves
in atoms --> explains Bohr’s
wave nature of the electron proved experimentally (Davisson & Gremer)
