Solving Wavelength & Tone of Sound Waves

Click For Summary

Homework Help Overview

The discussion revolves around sound waves, specifically focusing on the wavelength and tone produced by different setups, including a string and a Boomwhacker™ tube. The original poster presents a series of questions related to the fundamental frequency of 440 Hz and the physical characteristics of the systems involved.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants inquire about the necessary equations to determine wavelength and speed of sound in the given contexts. There is a request for clarification on the relationship between frequency, wavelength, and tube length. Some participants express uncertainty about how to approach the problems without specific formulas.

Discussion Status

The discussion is ongoing, with participants exploring various interpretations of the questions posed. Some guidance has been offered regarding potential resources, but there is no explicit consensus on the approach to take. The original poster's context of conducting an experiment adds a layer of complexity to the problem-solving process.

Contextual Notes

Participants note that the questions arise from a lab experiment rather than a formal class assignment, which raises concerns about the availability of necessary formulas and guidance. There is a suggestion to seek external resources for assistance.

(a) First, consider a string of length 1m attached at both ends. It sounding a fundamental tone of 440 Hz. What is the wavelength of the above waves on the string? What is the speed of the waves on the string?

(b) Now consider a Boomwhacker™ tube open at both ends, sounding a tone of 440 Hz. Given that the speed of sound in air is 330 m/s, how long is the Boomwhacker™ tube?

(c) What tone would be produced by the Boomwhacker™ tube if one end was capped.

What you tried so far? You need to show some of your thoughts on solving the problem. What equations might be useful?
 
These questions are not FOR a class, they just are questions that came up when I was doing an experiment in Lab Class. I'm not sure what route to take in order to solve it. It would be easier, as would many problems, if I were taking an actual physics class that supplied me with the formulas necassary for solving this problem.:rolleyes:

Questions that "came up" from where? They are still part of coursework though, right?
Read http://hyperphysics.phy-astr.gsu.edu/hbase/waves/string.html. Maybe that will help.

Try finding a book in the library to use as a reference.
