Chapter Pages
Three meaningful routes: concepts, laws, and model research.
32.1
Specters
How the light reports the composition of the substance
32.2
Quantum levels of the atom
The Bor model and its boundaries
32.3
Lasers
Compulsive radiation and intensity

32.1 Specters
- Dilated gas emits a lyenetic spectrum because atoms have discrete energy levels.
32.2 Quantum levels of the atom
- In the Bora model, the electron in the hydrogen atom has permitted fixed states and emits only between them; the model explains the spectrum of hydrogen, but gives way to quantum mechanics for complex atoms.
32.3 Lasers
- The laser uses forced radiation: the photon triggers the appearance of a second photon of the same frequency, phase, polarization and direction.
