👉 Waves, particularly those in fluids like water or air, are disturbances that propagate through the medium by transferring energy from one point to another without the bulk movement of the fluid itself. These waves can be classified into various types, such as surface waves, internal waves, and gravity waves. Surface waves, like ocean waves, involve the oscillation of water particles at or near the surface, influenced by factors such as wind speed and fetch. Internal waves occur within the fluid's layers, typically at the boundary between different densities, and can be driven by tidal forces or wind. Gravity waves, on the other hand, are oscillations caused by gravity acting on a fluid body, such as atmospheric pressure changes or seismic activity. The behavior of these waves is governed by the principles of fluid dynamics, including conservation of energy and momentum.
