SHM (restoring force)LC Circuits (Electromagnetism)Charge oscillates like displacement; I = dq/dt like v; ω = 1/√(LC) analogous to √(k/m)
Wave superpositionYoung's Double Slit (Optics)Constructive/destructive interference via path difference nλ and (n+½)λ
Doppler effect (sound)Doppler effect (light)Red shift (galaxy recession), blue shift; same formula but relativistic corrections at high v
Standing waves in stringsEM standing wavesMicrowave ovens use standing EM waves; nodes = cold spots (reason to rotate food)
Speed of sound v = √(γP/ρ)Kinetic theory of gasesγ = Cp/Cv connects thermodynamics; v ∝ √T ties to mean molecular speed
Wave energy ∝ A2A^{2}Intensity in sound/lightIntensity I ∝ A2A^{2}; inverse square law I ∝ 1/r2r^{2} for point sources
Beats (f_{1} − f_{2})InterferenceTemporal interference; spatial interference gives fringes in optics
