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 lowercase version of the Greek letter lambda (Î») is the standard symbol used to represent wavelength in physics and mathematics. The letter v represents velocity and Æ represents frequency.herefore, the wavelength of an A4 sound wave at 68Â° F is 343 m/s / 440 hz, which equals 0.7795 meters, or 77.95 cm. Waves in the electromagnetic spectrum, such as radio waves and light waves, have much shorter wavelengths than sound waves.
