How it Works

  • This calculator calculates the wavelength and half wavelength of sound in air with the formula


  • \lambda is wavelength, the Greek letter “L” for length.

  • f is frequency, measured in Hertz (Hz)

  • c is sound speed, measured in units of length per second.

  • The speed of sound in air is set to 343 m/s (1125.33 ft/s)

  • Answers are rounded to 2 decimal places
