The formula Vw = J• 1 describes the relationship between the speed of a wave (Vw), and its frequency (f) and wavelength (4).
For example, if a wave has a frequency of 120 Hz and a wavelength of 5m, it would have a speed of 600 m/s.
In one or two sentences, describe what would happen to the frequency of this wave if the wavelength is increased to 10m but the speed stays the same at 600 m/s.
