Wavelength vs Frequency
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.
Example Calculation
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
