For  radio waves and light waves  â scroll down â. Conversion: frequency f to wavelength Î» and wavelength to frequency. The speed of propagation c can be the speed of sound *or* the speed of light and radio waves. Sound waves are waves which propagate vibrations of air molecules.
We can calculate the wavelength of sound waves that we can hear using the formula wavelength = velocity / frequency. In air sound travels at about 340 meters per second (the precise value depends on temperature, humidity, and pressure). We hear (measured in air) range from about two-thirds of an inch to 50 feet.
