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.
To describe a wave, you need to know a few of its properties. One property is its wavelength. For a sound wave, this corresponds to how high or how low a note sounds. For a light wave, it corresponds to the colour of light. Another property is the amplitude, which corresponds to loudness for a sound wave or brightness for a light wave. One of the basic characteristics of a wave is its wavelength. This is the distance from one peak, or crest, to the next.
