Answer:
The relationship between the velocity of the wave, its wavelength and frequency is given by the formula
Wavelength\quad \lambda =\dfrac { Speed\quad (v) }{ Frequency\quad (\nu) } Wavelengthλ=
Frequency(ν)
Speed(v)
,
where, vv - velocity of the wave
\lambda λ - wavelength of the wave
ff - frequency of the wave.
In the question it is given that the frequency is 4.8 Hz and the wavelength is 6.0 cm, that is, 0.06 meters.
The velocity of the sound is calculated as follows.
v=f\times \lambda = 4.8 \ Hz\times 0.06 \ m = 0.288 \ m/sv=f×λ=4.8 Hz×0.06 m=0.288 m/s
Hence, the speed of the water wave is 0.288 m/s.
