Sound Characteristics of a Glass Bottle Containing Water at Different Levels HW Project topic is Measuring the speed of light using a microwave oven. *NOTE: the topic can be changed if you want to work on something different. (I’ll provide other project ideas upon request)

This project has 4 parts and each part of these 4 has to be done in a separate word document.

First part is Experimental Design:

Research the wave concepts that apply to this sound device and submit a brief proposal that includes your understanding of the physical principles and your experiment design.
Your design might be to arrange five identical glasses filled with different amounts of water. Measurements will be made using an app on your mobile phone, and a ruler. These will be related by the formula for a closed tube.
Make some predictions about the experiment results. Using your understanding of the physics, you can make an hypothesis about the resonance frequency and relative loudness from each glass, depending on how much liquid is in it.

Second Part is Experimental Data:

Perform this experiment by building the glass harp, filing the glasses with the amount of liquid you decided to use.
You can then take several pictures of your experiment set-up, too.
Measure the tones that are produced when you run your finger around the rim and record the data.

Third Part is Project Analysis

Graph your data. Show uncertainty estimates for your measurements and discuss sources of error (e.g. uncertainty in the ruler, positioning of the microphone).
Analyse the results by comparing your measured results to your hypothesis for the glass harp. How closely do the measurements match the theoretical model?

Last part is Final Report

Finally, you would use your analysis to make a final determination on the accuracy and reliability of your understanding of sound waves in a closed tube. You would make a short report summarizing all your work and reflecting on what you learned.
If you want, you can make a short video of your experiment or of you playing the harp.
