... A cold sodium atom (23Na), at rest, is isolated in a vacuum system on the Earth's surface. A laser, with λ = 589 nm (i.e., D-line or the 3s to 3p transition) shines on this atom from directly below. The atom absorbs photons and then reradiates that energy uniformly in all directions. Gravity, with a ...

Quantum Mechanics: Particles in Potentials
... As the quantum number increases to large values, probability of particle position approaches uniform distribution in the region [0,a]. This is the classical limit. Quantum mechanics approaches classical mechanics in the limit of large quantum numbers. As the quantum number increases to large values ...
