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.
In a classical sense, all waves have the property that their speed is a constant in any given medium, because the speed depends only on the properties of that medium, and not on the properties of the particular wave (like its energy, frequency, or wavelength) or the properties of the emitter.
