⚛️ Quantum Physics — Intro#

Scope — Fundamental principles governing matter and energy at atomic and subatomic scales.

Key concepts#

• Quantum physics — framework describing physical behavior where classical mechanics fails.
• Quantization — physical quantities take discrete values rather than continuous ranges.
• Wave–particle duality — entities such as electrons and photons exhibit both wave‑like and particle‑like behavior.

Seed Q&A triads#

• Q: Why is quantum physics needed in addition to classical mechanics?
  A: Classical mechanics cannot explain phenomena at very small scales, such as atomic spectra or electron behavior.

• Q: What does wave–particle duality mean?
  A: Quantum objects can display wave‑like interference and particle‑like localization depending on how they are observed.

• Q: What is meant by quantization of energy?
  A: Energy levels in atoms and other systems occur in discrete steps, not continuous values.
