Answer:
The distance between successive crests decreases.
Explanation:
If f is the frequency and [tex]\lambda[/tex] is the wavelength of a wave, then the speed of the wave is given by :
[tex]v=f\times \lambda[/tex]
on rearranging,
[tex]f=\dfrac{v}{\lambda}[/tex]
We know that wavelength of a wave is equal to the distance between successive crests or troughs.
If the frequency of a wave increases while its speed remains constant, the wavelength decreases i.e. the distance between successive crests decreases.
