• How Lasers Work: Stimulated Emission and Coherent Light
  A laser amplifies light through stimulated emission to make a narrow, coherent beam of one colour. Learn population inversion, the parts of a laser, and its uses.
• Heisenberg Uncertainty Principle
  The quantum mechanical limit on the simultaneous precision of position and momentum measurements: Δx·Δp ≥ ħ/2.
• Wave–Particle Duality
  The quantum-mechanical fact that entities such as light and electrons exhibit both wave-like and particle-like behavior depending on the experiment.
