Classical interpretation of Wave Motion

Click For Summary

Discussion Overview

The discussion revolves around the differences and similarities between classical physics of particles and classical physics of waves, particularly focusing on concepts such as momentum and the position of mechanical waves in space and time. The context includes theoretical exploration and clarification of concepts relevant to an academic assignment.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant expresses confusion about the differences in momentum interpretation between particles and waves.
  • Another participant questions how to describe the position of a mechanical wave.
  • Some participants emphasize the need for foundational understanding, suggesting that the equations for momentum and wave description should be reviewed first.
  • There is a concern raised about the appropriateness of the question in the forum context, with references to forum rules regarding homework-like inquiries.
  • A participant insists that the inquiry is not homework but rather a bonus question for an upcoming test, seeking clarification on classical wave definitions and formulas.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the appropriateness of the question for the forum, with some asserting it resembles homework while others focus on the conceptual inquiries regarding waves and particles.

Contextual Notes

There are indications of missing assumptions regarding the definitions of momentum and wave equations, as well as the context in which these concepts are being discussed. The discussion reflects varying levels of understanding among participants.

Who May Find This Useful

Individuals interested in the foundational concepts of classical wave and particle physics, particularly in the context of academic inquiry or test preparation.

Ive been learning a lot about how similar waves and particles are at the fundamental level, but today i was assaigned to discuss the difference between the CLASSICAL physics of particles vs Classical Physics of waves.
Differences and similarities and well as how momentum is/isnt diferent as well as if a wave can be said to be in/at a certain point in space at a given point in time.
Hope that made sense, Thanks!

Your description of your assignment made sense. But what is your question?
 
grammar error

Do we interpret momentum any different with waves?
How do we describe a mechanical waves position?
 
There's a difference between asking for help about something that confuses you, and just asking us to do your homework for you! Do a bit of research first and let us know if there is something you don't understand. At the very least, tell us what you do know about waves that might be relevant to your project. When we know what you know, we'll be able to help you figure out what you don't know. You know?:biggrin:
 
No no no! This isn't homework at all! Its a bonus question on a test i have coming up, and everywhere i look online i can only find either how they are similar (quantum mechanics) or their definitions.

I was just curious if there is a difference in any of our formulas or definitions that changes when talking about classical waves. thanks though!

Why don't you read the forum rules?

"As a reminder, please do not post Homework/Schoolwork-type questions here. We have a dedicated forum for that:

Homework, Coursework, & Textbook Questions

This rule applies even if your question is not formally part of a HW/Coursework. Any type of question that has the same resemblance to that covered in a typical schoolwork must be posted in that forum, not in here.

Zz. "

You're in the wrong room.
 
Well before you can start asking about these kind of questions you need to look at the physics first - what is the equation for the momentum carried by a wave? What does the equation which describes a wave look like?

Start by writing these down, and then try to understand what they "mean" as best you can. That's how you have to understand things.
