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.

1 answer

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