How can I solve 15.11 C in my Mechanical Waves Homework?

Click For Summary

Discussion Overview

The discussion revolves around solving a specific problem from a mechanical waves homework assignment, specifically question 15.11 C. Participants are seeking assistance in understanding the concepts and methods required to approach the problem.

Discussion Character

  • Homework-related, Conceptual clarification

Main Points Raised

  • One participant expresses confusion about how to solve the problem and requests help, indicating a lack of understanding of the necessary concepts.
  • Another participant asks what the original poster has tried, suggesting a collaborative approach to problem-solving.
  • A later reply mentions that the instructor described the solution as complicated, prompting a request for hints or guidance.
  • One participant introduces the concept of wave speed and its relation to observation, prompting further inquiry into how this relates to the problem at hand.
  • Another participant suggests that the problem is not overly complicated but requires a fundamental understanding of physics principles, using the analogy of determining the speed of a car.
  • A participant notes the formula for velocity as distance/time but expresses uncertainty about how to apply it due to missing time information.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the complexity of the problem or the best approach to solving it. Multiple viewpoints on the difficulty and necessary understanding remain present.

Contextual Notes

There is an indication of missing information, particularly regarding time, which may be critical for solving the problem. The discussion reflects varying levels of understanding among participants.

Thank you so much for your attention ,Actually I do not have a clue how o do it . My instructor said the way to solve it is very complicated. So can you give me a hint or tell how to do that .Thank you again .
 
Suppose you are looking at a wave traveling past you. What does wave speed mean, in relation to what you are seeing?

Now how does the figure relate to the wave speed?

I don't think it is complicated so much as requires that you understand the physics somewhat.
ie. how would you normally be able to find out the speed of something - say, a car?
 
The distance / time = velocity . But I do not jab the time here .
 
Thread locked. @Simon Bridge -- please PM the OP and explain the PF Homework Help rules.
