Answer : The wavelength of the sound signal is 6.30 m.
Explanation :
Formula used :
[tex]\lambda=\frac{c}{\nu}[/tex]
where,
[tex]\lambda[/tex] = wavelength of sound signal = ?
[tex]\nu[/tex] = frequency = [tex]230Hz=230s^{-1}[/tex]
c = speed of sound under water = [tex]1.45\times 10^3m/s[/tex]
Now put all the given values in the above formula, we get:
[tex]\lambda=\frac{1.45\times 10^3m/s}{230s^{-1}}[/tex]
[tex]\lambda=6.30m[/tex]
Therefore, the wavelength of the sound signal is 6.30 m.
