Topics covered in Wave Motion for JEE Advanced Physics.
Topics in Wave Motion
1
1. Introduction and Classification of Waves
- A wave transfers oscillations, energy, and momentum without transferring matter
- Physical quantity 'y' oscillates at one point and propagates to other points
- Three types of classification: dimensional (1D, 2D, 3D), directional (transverse, longitudinal), and mechanical nature (mechanical, non-mechanical)

2. Equation of Travelling Wave
- Wave equation: ∂²y/∂t² = v²(∂²y/∂x²) where v is wave speed
- General solution: y(x,t) = f(ax ± bt) represents a travelling wave
- Wave speed v = b/a = coefficient of t/coefficient of x

3. Sine Wave and Wave Parameters
- Sine wave: y = A sin(ωt ± kx ± φ) where A = amplitude, ω = angular frequency, k = wave number, φ = phase
- Angular frequency: ω = 2πf = 2π/T, where f = frequency, T = time period
- Wave number: k = 2π/λ, where λ = wavelength

4. Wave Graphs and Phase Analysis
- y-x graph (t = constant): snapshot of wave at fixed time showing spatial variation
- y-t graph (x = constant): shows temporal variation of one particle's motion
- Phase difference between particles: Δφ = (2π/λ)Δx = kΔx
