Is Wave Phenomena Related to PDE or Just Physics?

Click For Summary

Discussion Overview

The discussion centers on the relationship between wave phenomena and partial differential equations (PDE) versus their connection to physics. Participants explore whether wave phenomena are primarily a mathematical concept or if they are inherently tied to physical principles, considering both theoretical and educational perspectives.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Some participants propose that wave phenomena are related to PDE, specifically mentioning dispersive wave equations and their qualitative study.
  • Others argue that wave phenomena are also a significant topic in physics, often taught separately in introductory and advanced courses.
  • A participant highlights the Schrödinger wave equation as an example of a dispersive equation encountered in quantum mechanics.

Areas of Agreement / Disagreement

Participants generally agree that wave phenomena are related to both PDE and physics, but the extent and nature of this relationship remain somewhat contested.

Contextual Notes

The discussion does not resolve the specific definitions or implications of wave phenomena in relation to PDE and physics, leaving open questions about the boundaries of each field.

Hey! :o

Do you know if "Wave Phenomena" are related to PDE or only to physics?? (Wondering)

There is a large class of PDE known as dispersive wave equations. These equations are usually studied qualitatively. For example, one seeks to determine if solutions propagate in finite time or if they exist globally. If you've studied quantum mechanics, then you've seen a dispersive equation -- the Schrödinger wave equation.

Ok! Thank you for the information! (Yes)
 
I would definitely say that wave phenomena are definitely related to both fields. Waves are described using PDE's, so they're related to that field; on the other hand, you usually study waves as a separate topic in most first-year physics courses, as well as more advanced physics courses where you actually solve the PDE.
