Semiclassical descriptions involve a base/background part described classically, and quantum parts representing an effective development in powers of Planck's constant, ħ. They cover systematic approximations such as the WKB, intuitive approaches to the correspondence limit, and a broad class of interstitial physical phenomena.

How can Planck's constant take different values?
In a purely classical (Newtonian) universe, quantum effects would be absent, and the way to pretend this is true mathematically is to allow Planck's constant to approach zero, and see what the consequ …

Does spin really have no classical analogue?
Niels adds a minor point, and in typical fashion omits the math which is beyond his comprehension (which is to say, all of it):
The best example that I can think of which illustrates that QM spin has …

Quantum properties of long wavelength electromagnetic radiation
I will assume here that by "long wavelength" you mean longer than ~150 meters (i.e., in the AM radio band).
It is true that all EM radiation exists in quanta, each photon with energy E = (planck's con …
