Answer : The wavelength of the sound signal is 6.30 m.

Explanation :

Formula used :

$\lambda=(c)/(\\u)$

where,

$\lambda$ = wavelength of sound signal = ?

$\\u$ = frequency =
230Hz=230s^(-1)

c = speed of sound under water =
1.45* 10^3m/s

Now put all the given values in the above formula, we get:

$\lambda=(1.45* 10^3m/s)/(230s^(-1))$

$\lambda=6.30m$

Therefore, the wavelength of the sound signal is 6.30 m.
