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.
How does the speed of a wave relate to its frequency and wavelength? Speed of wave (e.g. m/s) = wavelength (m) x number of waves per second (Hz) So you can figure out any one of speed, wavelength or frequency if you know the other two. Often, â¦ you know the speed (e.g. light, 3x10^8 m/s, or sound, 340 m/s).
