Waves — Key Formulas
| Formula | Expression |
|---|---|
| Wave Equation | v = fλ (velocity = frequency × wavelength) |
| Wave Speed (String) | v = √(T/μ) (tension/linear mass density) |
| Intensity | I = P/A = ½ρvω²A² |
| Doppler Effect | f' = f × (v ± v_observer)/(v ± v_source) |
| Beats | f_beat = |f₁ − f₂| |
| Sound Intensity Level | β = 10 log(I/I₀) dB |
