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.
Wavelength is described as a function of speed and frequency of the propagation of that wave. Longer wavelengths are associated with lower frequencies, and smaller wavelengths are associated with higher frequencies. Wave velocity, also known as water waves, is considered constant.
