The formula vw=f⋅λ

describes the relationship between the speed of a wave (vw
), and its frequency (f
) and wavelength (λ
).

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.

The frequency of the wave would decrease to 60 Hz, since the speed of the wave is constant and the wavelength is doubled.

If the wavelength is increased to 10m but the speed remains the same at 600 m/s, the frequency of the wave would decrease to 60 Hz.

If the wavelength is increased to 10m but the speed of the wave remains the same at 600 m/s, the frequency of the wave would decrease.
