A $1\mathrm{.}1$ m high sinusoidal wave propagates with a celerity of $10\frac{m}{sec}$ in deep sea$-$water. Determine

the period and the length of this wave $(4$ points$).$ Draw the vectors $($relative to the direction of the

wave$)$ and determine the magnitudes of the velocity and of the acceleration of the fluid particles

on the free$-$surface of the wave at a distance of $\frac{L}{4}$ from the wave crest in the direction of the

wave propagation $(L$ is the wave length$).(10$ points$)$
