LECTURE 2. THE DEVELOPMENT OF QUANTUM MECHANICS
LECTURE 2. THE DEVELOPMENT OF QUANTUM MECHANICS

... v = velocity amd h = Planck’s constant.. Note the inverse relationship of m and λ. Which means that a 1g mass (very heavy) at 1m/s has λ = 7 x 10-33m, but 1 proton at speed of light has λ = 1 x 10-11m. Uncertainty Principle: If photons are waves, then in the same way we can’t say what the location o ...

... We demonstrate the experimental realization of Bohr -like atoms by applying a pulsed unidirectional field, termed a half-cycle pulse (HCP), to atoms in quasi-two-dimensional nearcircular states. This leads to creation of localized wave packets that travel in near-circular orbits and mimic the dynami ...

... The wave-particle duality is fundamental to quantum mechanics. Light can behave like a particle (photon); matter can behave like a wave. The wavelength associated with a particle is inversely proportional to its momentum p: λ = h / p, where h is Planck’s constant. For cold atoms, the wavelength is l ...

... momentum p = mv. If the electron and proton have the same momentum, they cannot have the same speed because of the difference in their masses. For the same reason, remembering that KE = p2/2m, they cannot have the same kinetic energy. Because the kinetic energy is the only type of energy an isolated ...
