What is Quantum Mechanics?
The branch of physics describing the behavior of matter and energy at atomic and subatomic scales. Quantum mechanics introduces the wave-particle duality of matter, quantization of energy, the uncertainty principle, and electron orbitals. It forms the foundation of modern atomic and molecular theory.

The branch of physics describing the behavior of matter and energy at atomic and subatomic scales. Quantum mechanics introduces the wave-particle duality of matter, quantization of energy, the uncertainty principle, and electron orbitals. It forms the foundation of modern atomic and molecular theory.
Quantum mechanics is applied in: explaining atomic spectra and electronic structure, designing semiconductor devices (transistors, LEDs, solar cells), quantum computing (exploiting quantum superposition and entanglement), NMR (nuclear spin energy levels in magnetic field), laser technology (stimulat…
Quantum tunnelling (a quantum mechanical phenomenon) allows particles to pass through energy barriers — relevant in: enzyme catalysis (proton tunnelling), radioactive alpha decay (tunnelling through Coulomb barrier), and scanning tunnelling microscopes (STM).
