Compute the wave number $k$ and wave length $L_w$ according to linear wave theory as a function of wave frequency $$ for the following set of water depths hin$[1\mathrm{.}5m,1\mathrm{.}829m,2\mathrm{.}0m,4\mathrm{.}0m,8\mathrm{.}0m].$ Plot the results for all five water depths into a single figure with the wave frequency as $x-$axis and the wave length as $y-$axis. For the wave frequency use a range of $0\mathrm{.}2ra\frac{d}{s}$ to $4\mathrm{.}0ra\frac{d}{s}.$ Cut off the plot at a reasonable wave length.I
