SUMMARY
The discussion clarifies the distinction between phase velocity and group velocity in wave mechanics. Phase velocity is defined as the ratio of angular frequency (ω) to wave number (κ), expressed mathematically as ω/κ. In contrast, group velocity is determined by the derivative of angular frequency with respect to wave number, represented as dω/dκ. Understanding these definitions is crucial for analyzing wave propagation and behavior.
