📜 1. Foundations of Modern Physics & Relativity

Special Theory of Relativity: Michelson-Morley experiment, Lorentz transformations, length contraction, time dilation, mass-energy equivalence (E=mc²).
Atomic Mechanics: Relativistic corrections to subatomic motion and momentum.

🔬 2. Properties of Charged Particles & Early Models

Charged Particles: Study of electron dynamics, determination of specific charge (e/m), Thomson’s method, and Millikan’s oil drop experiment.
Early Atomic Schemes: Thomson’s plum pudding model, Rutherford’s alpha-particle scattering experiment, and the concept of the atomic nucleus.

⚛️ 3. Quantum Theory of the Atom

Bohr’s Atomic Theory: Postulates of the Bohr model, calculation of radii, velocity, and energy levels for hydrogen-like atoms.
Atomic Spectra: Origin of spectral series (Lyman, Balmer, Paschen, etc.), Ritz combination principle, and Rydberg constant adjustments for finite nuclear mass.
Sommerfeld’s Extension: Relativistic Bohr-Sommerfeld model, elliptical orbits, and fine structure of hydrogen lines.

🌟 4. Vector Atom Model & Quantum Numbers

Quantum Numbers: Principal (n), orbital (l), magnetic (m), and spin (s) quantum designations.
Coupling Schemes: L-S (Russell-Saunders) and j-j coupling configurations for multi-electron elements.
Exclusion Principle: Pauli’s exclusion principle and the structural electronic build-up of the periodic table.

🧲 5. Magnetic Anomalies & X-Rays

Magnetic Interactions: Stern-Gerlach experiment, Bohr magneton, Normal and Anomalous Zeeman effect, and the Stark effect.
X-Ray Physics: Production of continuous and characteristic X-ray spectra, Moseley’s Law, Bragg’s Law of X-ray diffraction, and the Compton scattering effect.
