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.
The wavelength and the frequency of the sound waves from the police car is the same in all directions. Therefore, observers on any side of the police car would hear the exact same sound. Remember the wave equation, We know the speed of sound in air is 330m/s and the wavelength for the sound waves from the siren are 1m.
