Vedatom Physics Waves & Oscillations / ▤ The Full Book
Phase & sign — quick reference
Oscillation: y = A·sin(ωt + φ) — φ sets the head start. +φ leads, −φ lags.
Travelling wave: y = A·sin(kx − ωt) moves in +x; kx + ωt moves in −x.
Relations: ω = 2πf, k = 2π/λ, v = ω/k = fλ.
Particle velocity ∂y/∂t ≠ wave velocity v. A crest is where phase = π/2.

The Full Book

The whole of oscillations, waves and sound, written to read start to finish — every derivation, worked example and exam-ready problem bank, with the live benches embedded inline at the moment each idea appears.

The books

two volumes · JEE-Advanced depth
01 Simple Harmonic Motion
The full sweep of oscillations — the kinematics x = A·sin(ωt+φ) and its phasor, the restoring-force condition, energy exchange, simple and physical pendulums, spring combinations, damping, forced resonance and the superposition of SHMs.
31 examples · 50-question bank · 6 benches · 13 diagrams

02 Waves & Sound
Waves from first principles — transverse and longitudinal motion, the wave equation and wave speed, energy and intensity, superposition and standing waves, sound and the pressure wave, resonance in pipes, beats, the Doppler effect and shock waves.
30 examples · 50-question bank · 8 benches · 13 diagrams

The six Lab modules are woven across these two books — Oscillations & SHM into Simple Harmonic Motion; wave motion, standing waves, sound, beats and the Doppler effect into Waves & Sound.
