The formula, VW equals F times X describes the relationship between the speed of a wave and its frequency and wavelength. For example if a wave has a frequency of 120 Hz and a wave length of 5 m, it would have a speed of 200 m/s in one or two sentences describe what would happen to the frequency of this wave if the wavelength is increased to 10 m, but the speed stay is the same at 600 m/s
If the wavelength is increased to 10 m but the speed remains at 600 m/s, the frequency of the wave would decrease to 60 Hz. This is because the speed of the wave remains constant, so as the wavelength increases, the frequency must decrease in order to maintain the same speed of the wave.
