Quantum Physics

The field of quantum physics studies the behavior of matter and energy at the scales of atoms and subatomic particles where physical parameters become quantized to discrete values. Wolfram|Alpha provides information on many quantum mechanics systems and effects. Calculate wavelengths, energy levels and spectra using quantum theory.
