Master Wave Propagation Physics: Phase, Group, Signal Velocity
Understanding Wave Propagation: Beyond Simple Speed We often talk about the "speed of a wave," but this is a simplification. To truly master wave propagation, we must understand the nuanced differences between phase, group, and signal velocities. These three velocities, while related, often differ significantly, especially in dispersive media. This guide will clarify these concepts, providing a step-by-step approach to understanding and calculating them. For a deeper dive into wave phenomena, check out this helpful resource....
