Wavelength vs Frequency
Formula
## Sound Wavelength with Temperature The speed of sound in air increases with temperature, which affects the wavelength. ### Formulas **v_sound = 331.3 + 0.606 * T** (in m/s, T in Celsius) **lambda = v_sound / f** Higher temperatures produce longer wavelengths at the same frequency.
Esempio Risolto
Concert A (440 Hz) at 20 degrees Celsius.
- 01v = 331.3 + 0.606 * 20 = 343.42 m/s
- 02lambda = 343.42 / 440
- 03lambda = 0.7805 m

Why does temperature affect the speed of sound?
Higher temperature means faster-moving air molecules, which transmit pressure waves more quickly.
Is this formula accurate at extreme temperatures?
The linear approximation works well from about -20 to 40 degrees Celsius. Beyond that range, more precise models are needed.
Does humidity affect the speed of sound?
Yes, slightly. Humid air is less dense than dry air (water vapor is lighter than N2/O2), so sound travels a bit faster in humid conditions.
