The formula describes the relationship between the speed of a wave and its frequency and wavelength for example if a wage has a frequency of 128 Hz and a wave length 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 week if the wave link is increased to 10 m but the speed stays at 600 m/s
If the wavelength is increased to 10m while the speed stays the same at 600 m/s, the frequency of the wave would decrease. This is because the speed of the wave remains constant, so the frequency must decrease in order to maintain the new wavelength.
