IF a wave moving at a constant speed were to have it's wavelength doubled (Wavelength x 2), then the frequency of the wave would be half of what it originally was (Frequency / â¦ 2). 6 people found this useful. Al Cohen.
If you increase frequency you decrease wavelength, at the same wave velocity. The speed of a mechanical wave in a medium depends on 2 things an elasticity term (on the top) an mass/inertia/density term (on the bottom) The greater the restoring force in the medium, the greater the speed of the waves.t doesn't. Apart from light in a vacuum, the speed of a wave in a medium will vary with frequency or wavelength. It's called dispersion. Apart from light in glass, which is well known, the speed of sound in gases in some cases will increase with frequency. At higher frequencies in CO2 for example.
