The wave travels at the speed of sound in water: [tex]v=1500 m/s[/tex].
The frequency of the wave is
[tex]10 ms^{-1} = 10000 s^{-1} = 10000 Hz[/tex]
so we can find its wavelength [tex]\lambda[/tex] by using the basic relationship between frequency, wavelength and speed of the wave:
[tex]\lambda= \frac{v}{f}= \frac{1500 m/s}{10000 Hz}=0.150 m = 15 cm [/tex]
