Hz (T in N, μ in kg/m)
Transverse standing wave resonances produced along stretched flexible strings fixed at both ends.
f_n = (n / 2L) √(T / μ), v = √(T / μ)

Waves, Oscillations & Acoustics
N/A
The phenomenon where wave phase velocity depends on wave frequency or wavelength in a medium.
v_p = f(λ), d²ω/dk² ≠ 0

rad/m (or m⁻¹)
A spatial frequency measure expressing the number of radians or wave cycles per unit distance.
k = 2π / λ

Waves, Oscillations & Acoustics
m
A short localized burst or envelope of wave energy formed by the superposition of multiple waves with slightly different frequencies.
Δx Δk ≥ ½
Waveform
Waves, Oscillations & Acoustics
N/A
