The frequency (f), wavelength (λ) and speed (v) of a sound wave are related as

The fundamental wave equation states that the speed of a wave equals the product of its frequency and wavelength: v = fλ (or equivalently v = λf). This relationship holds for all types of waves including sound waves. Frequency is measured in Hertz (Hz), wavelength in meters (m), and speed in meters per second (m/s). For sound in air at room temperature, the speed is approximately 343 m/s.
