: These occur within stratified fluids (where density varies with depth, like in the ocean or atmosphere). These waves are unique because their group and phase velocities can be perpendicular or even oppositely directed. Key Scientific Contributions

In the 1960s, Sir James Lighthill, a renowned British mathematician and physicist, introduced the concept of Lighthill waves while studying the generation of sound waves by turbulent flows. He realized that the waves generated by turbulence in a fluid could be described using a new mathematical framework, which led to the development of Lighthill's theory of wave generation by turbulence. lighthill waves in fluids pdf

: Lighthill explores how large-amplitude waves steepen into shock waves or hydraulic jumps through simple wave theory. 3. Water Waves He realized that the waves generated by turbulence
