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

Click For Summary
SUMMARY

The discussion centers on solving problem 15.11 C from a Mechanical Waves homework assignment, specifically regarding the concept of wave speed. Participants emphasize the importance of understanding the relationship between distance and time to calculate wave speed, akin to determining the speed of a car. The complexity mentioned by the instructor is attributed to the need for a solid grasp of physics principles rather than the problem itself being inherently difficult. The thread was subsequently locked for adherence to forum rules.

PREREQUISITES
  • Understanding of basic physics concepts, particularly wave mechanics.
  • Familiarity with the formula for calculating speed: distance/time.
  • Knowledge of how to interpret graphical representations of waves.
  • Experience with problem-solving in a physics context.
NEXT STEPS
  • Review the principles of wave speed in Mechanical Waves.
  • Study graphical analysis of wave properties and their implications.
  • Practice solving similar physics problems involving distance and time calculations.
  • Explore resources on the fundamentals of wave mechanics and their applications.
USEFUL FOR

Students studying physics, particularly those tackling Mechanical Waves problems, educators seeking to clarify wave concepts, and anyone looking to improve their problem-solving skills in physics.

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.
