Topics in Waves and Sound
1
Wave Motion and Characteristics
- Waves transfer energy and momentum without transferring matter
- Mechanical waves require a medium; electromagnetic waves do not
- Transverse waves: particle motion perpendicular to wave direction (e.g., string waves)
2
Sound Waves and Velocity
- Sound waves are longitudinal mechanical waves requiring a medium
- Sound travels fastest in solids, slower in liquids, slowest in gases
- Newton assumed isothermal process: v = √(P/ρ) - gave wrong result
3
Progressive Wave Equation
- Standard form: y = a sin(ωt ± kx ± φ₀)
- Negative sign: wave travels in +x direction; Positive sign: wave travels in -x direction
- Particle velocity: v_p = ∂y/∂t = aω cos(ωt - kx)
4
Superposition and Interference
- Principle of superposition: resultant displacement = sum of individual displacements
- Constructive interference: waves meet in same phase (path difference = nλ)
- Destructive interference: waves meet in opposite phase (path difference = (n+1/2)λ)
