21. You can see this with water waves sometimes. 22. Similar concept has also been extended to applications in the analysis of offshore platforms under water waves . 23. The brick wall which runs along the moat and Bogambara lake is known as water waves wall. 24. Water waves of different wave lengths travel with different phase speeds, a phenomenon known as frequency dispersion.25. :The sound wave is like a water wave , the particles in the air's displacement is theoretically zero. 26. Some of the most common examples of mechanical waves are water waves , sound waves, and seismic waves. 27. Her dissertation, supervised by John J . Mahony, was entitled " Water Waves above a Sill ". 28. More generally, the Stokes drift velocity is the difference between the average his 1847 study of water waves . 29. For water waves, this is already the case; water waves propagate only on the surface of the water. 30. Several exact relationships exist between integral properties such as conservation laws for water waves , through Noether's theorem.
