Modern Physics

Modern Physics

Physics beyond classical mechanics — where quantum ideas, relativity, and microscopic structure redefine our understanding of nature.

Modern physics explains phenomena that classical physics cannot — atomic stability, radiation, semiconductors, nuclear energy, and the quantum behavior of matter.

Quantum Foundations

Blackbody radiation, photoelectric effect, wave–particle duality, de Broglie wavelength, and the breakdown of classical ideas.

Open Topic

Atomic Structure

Bohr model, energy levels, spectra, and the quantum explanation of atomic stability.

Open Topic

Nuclear Physics

Nuclear binding energy, radioactivity, nuclear reactions, fission, fusion, and mass–energy equivalence.

Open Topic

Semiconductors & Solid State

Band theory, conductors–insulators–semiconductors, p–n junctions, diodes, and the physics behind electronics.

Open Topic

Relativity (Foundations)

Special relativity, space–time concepts, time dilation, length contraction, and relativistic energy.
