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.
