GATE PH study guide
GATE PH · Work through your exam, one topic at a time.
GATE - the Graduate Aptitude Test in Engineering - is a computer-based examination conducted jointly by the Indian Institute of Science (IISc), Bangalore, and the Indian Institutes of Technology (IITs) on behalf of the Ministry of Education (MoE), Government of India. It tests a candidate's comprehensive understanding of undergraduate subjects in Engineering/Technology/Architecture and of post-graduate level subjects in Science. The GATE PH study guide has 10 sections and about 3,110 words.
01Mathematical Physics
Mathematical Physics in GATE PH tests the analytic machinery used across physics: complex analysis, linear algebra, differential equations, vector calculus, transform methods, and probability. Questions typically combine a standard technique with a physical boundary condition, so most marks are lost while setting up the problem rather than during the final algebra.
332 words, about 2 min02Classical Mechanics
Classical Mechanics in GATE PH tests Lagrangian and Hamiltonian formulations, central-force motion, small oscillations, rigid-body dynamics, canonical transformations, and Poisson brackets. The exam favours problems where a clever generalised coordinate removes constraints and exposes a simple conserved quantity.
296 words, about 1 min03Electromagnetic Theory
Electromagnetic Theory in GATE PH tests Maxwell's equations, boundary conditions, scalar and vector potentials, gauge choices, Poynting's theorem, plane waves, waveguides, and radiation. Numerical questions often ask for a reflection coefficient, skin depth, cutoff frequency, or energy density.
362 words, about 2 min04Quantum Mechanics
Quantum Mechanics in GATE PH tests the postulates, operator algebra, commutators, angular momentum, exactly solvable systems, perturbation theory, variational methods, WKB approximation, scattering, and identical particles. The exam often rewards recognising a symmetry or a standard result before doing a long integral.
278 words, about 1 min05Thermodynamics and Statistical Physics
Thermodynamics and Statistical Physics in GATE PH tests the laws of thermodynamics, thermodynamic potentials, Maxwell relations, ensembles, partition functions, quantum statistics, and phase transitions. Questions often ask for a derivative, a heat capacity, or the classical limit of a quantum distribution.
309 words, about 2 min06Atomic and Molecular Physics
Atomic and Molecular Physics in GATE PH tests hydrogenic spectra, fine structure, electron spin, LS coupling, term symbols, selection rules, rotational and vibrational spectra, Raman scattering, and basic magnetic resonance. The exam often uses a spectrum spacing or a term symbol to test a compact calculation.
308 words, about 2 min07Solid State Physics
Solid State Physics in GATE PH tests crystal structures, Miller indices, reciprocal lattices, Bragg diffraction, phonons, free-electron and band theory, semiconductors, magnetism, and superconductivity. Numerical questions frequently use a cubic crystal and a diffraction angle.
308 words, about 2 min08Nuclear and Particle Physics
Nuclear and Particle Physics in GATE PH tests nuclear size and binding energy, the semi-empirical mass formula, radioactive decay, nuclear reactions, cross sections, conservation laws, the quark model, and basic particle classifications. Questions often turn on a mass defect or a conserved quantum number.
296 words, about 1 min09Electronics
Electronics in GATE PH tests semiconductor devices, diodes, bipolar and field-effect transistors, operational amplifiers, feedback, oscillators, digital logic, and basic communication circuits. The exam often uses an ideal-device approximation and expects you to identify the operating region before calculating.
330 words, about 2 min10General Aptitude
General Aptitude in GATE PH tests numerical ability, logical reasoning, data interpretation, and verbal ability. The section is scoring because the mathematics is elementary, but the wording is designed to punish rushed reading and unit slips.
