22 Official 2024 Lecturer Disciplines — Syllabus Directory · Subjects 12–22

Useful for: SSB Lecturer (Degree Colleges)

Overview

Postgraduate physics covers classical mechanics, electromagnetism, thermodynamics and statistical mechanics, quantum mechanics, optics, solid state, nuclear physics and electronics.

Key points

Classical mechanics: Newtonian, Lagrangian and Hamiltonian formulations.
Electromagnetism: Maxwell’s equations.
Thermodynamics and statistical mechanics.
Quantum mechanics: Schrödinger equation, Heisenberg uncertainty principle.
Solid state physics and semiconductors.
Nuclear and particle physics; electronics.

Explanation

Maxwell’s equations unify electricity and magnetism.
The uncertainty principle limits simultaneous position and momentum precision.
Band theory explains conductors and insulators.
Problem-solving practice is essential.

Step by step

Place the question in its unit of the syllabus.
Recall the theory, thinker, law or work involved.
Eliminate options from other schools, periods or units.

Examples

Equations unifying electricity and magnetism → Maxwell’s.
Limit on knowing position and momentum together → Heisenberg.
