Overview

• Transverse waves on a string
  
• Continue to work in the same groups
  

Project

• Overview of how to do the project:
• You will need one file for this project
• For the project and report, download and open the matlab file   e4122p06stringWave_m.mlx   and answer all the questions (see report requirements below)
• You will simulate a transverse traveling wave pulse on a string
• You will simulate transverse standing waves on a string

• Though not required, you may be interested in video file  guitarLowEb.mp4 which is a slow-motion video of an acoustic standing wave experiment
  
• The video shows a standing wave on a guitar string in slow motion as below

Fig. 01

• As part of the project, the matlab simulation will show the propagation of the transverse traveling wave pulse down a line as illustrated below

Fig. 02

• As part of the project, the  maatlab simulation will also show videos of the transverse traveling wave pulse traveling down the line as below (you may need to reload this webpage to see the animation)
  

Fig. 03

• As part of the project, the  maatlab simulation will also show a transverse standing wave for transverse velocity on a string as below (same type of format as Fig. 1)

Fig. 04

• As part of the project, the  maatlab simulation will also show videos of the transverse standing wave as in the mode n=2 example below (you may need to reload this webpage to see the animation)

Editing the maatlab file

• The matlab script should open in the live editor (magenta arrow below) as shown below
• Make sure the live editor opens in the output-on-right mode (blue arrow below)

FIg. 03

• The script file is on the left (blue box above) and the output generated is on the right (magenta box above)
  
• Run the script by pressing the run button (magenta circle above)
  
• Read through the script and make any changes that are requested
• Save your file frequently
  
• Answer all questions by filling in the answers in the script such as:
•  disp(' Answer: this is my answer')
• at the appropriate places in the script
• this will place your answers in the pdf-printout when the script runs after you export a pdf of the project (instructions below)

PROJECT REPORT

• To export a pdf of your report:
• First, the project should be opened in "Maatlab Live Editor"(magenta arrow below) to export a pdf.
• Make any needed maatlab changes per any questions in the project.
• You must re-run the script for changes to take effect (blue circle below)
  
• Answer all numbered questions below, Q1, Q2, etc.
• Select the "Hide Code" format (blue arrow below) before exporting your pdf
• In live editor, use Save::export-as-pdf (magenta circle below) to print the report
• DO A FINAL CHECK of your pdf before turning it in.
• Once your file is exported, it should look like this example report.

• DONT FORGET TO SAVE YOUR FILES!

• Tips:
  
• Download any missing toolboxes as prompted
