Sound Wavelength Calculator

Find the wavelength of a sound from its frequency.

Wavelength 0.7795

Formula: λ = speed ÷ frequency

Step-by-step with your numbers:
1. Values used:
2. Frequency = 440 Hz
3. Speed of sound = 343
4.
5. Wavelength = Speed of sound / Frequency = 343 / 440 = 0.7795
Did we solve your problem today?

A sound wave's wavelength is the distance between successive compressions.

The math behind it

λ = c ÷ f. Lower notes have longer wavelengths.

Worked example

440 Hz (concert A) in air → about 0.78 m.

FAQ

Why do bass notes need big speakers?

Their long wavelengths couple better to large diaphragms.
