Waves with a period T $=8$ seconds and height H $=3$ meters impinge upon a breakwater at an angle of $135$o$.$ The water depth at the tip of the breakwater toe is d $=5$ meters.

Find the wave height at a point having coordinates in units of wavelength x $=3$ and y $=4.$

Find the radial distance from the breakwater tip at the same coordinates.

Find the wave height at the point which is $170$m away from the breakwater tip when $\backslash$beta $=60$o$.$
