Given:

The speed of the wave is v = 12 cm/s = 0.12 m/s

The wavelength of the wave is

$\lambda\text{ = 0.4 m}$

To find the period.

Step-by-step explanation:

The time period can be calculated by the formula

$T=(\lambda)/(v)$

On substituting the values, the time period will be

$\begin{gathered} T=(0.4)/(0.12) \\ =3.33\text{ s} \end{gathered}$

Thus, the time period of the sea wave is 3.33 s
