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.
f is frequency. l is wave length. so in solution, changing the speed of sound must mean having the sound/wave go through another medium, eg. water. I'm not sure how else you can change the speed of sound. In general, you can't change the length of the wave so when v is 10% larger, f is 10% larger. The speed of sound is constant. The frequency of sound is governed by the equation s=fx, where x is the wavelength, f is the frequency, and c is the speed of sound. Therefore, frequency and wavelength are inversely proportional.
