Two pressure sensors are located at the seafloor: one is 100 m and the other is 500 m off the coastline. For a wave train of 10-s period, the pressure sensor closer to the shoreline measures the pressure amplitude as 5911 Pa and the other sensor measures the pressure amplitude as 4987 Pa. Given that the wave height is H = 1.5 m, what is the average bathymetric slope between the two pressure sensors? Assume that the wave height has negligible variation between the two observation points. Take the magnitude of the gravitational acceleration as 9.81 m/s2 and the density of the seawater as 1000 kg/m3.
