Terms and Definitions:
Wavelength (λ): the distance of one full wave; example- crest to crest
Frequency (f): number of waves or vibrations in a unit of time Period (T): time between waves/ vibrations (time for one λ to pass) Wave Speed (V): rate at which a wave travels Amplitude (A): displacement from equilibrium to crest I a wave Transverse Wave: moves up and down as it travels forward Longitudinal Wave: compresses and expands as it moves forward |
This is us building our guitar.
This is our drumset above. We decided to make this one without notes because the metal didn't make a great noise.
Our xylophone is to the left. We used the equation in the document below to find the length of the chimes.

Below is the document that all four of us wrote describing how each instrument works and why.
Reflection
Overall, this project was great. A good thing was my group. We worked really well together and got a lot done; we made a whole extra instrument! I have to admit, a hardship was the math of the project, and finding our formulas. An especially hard instrument for this was the bottles. There was no actual formula, so we did a lot of guessing and checking until we sort of figured out how it worked (see details in the above document). A really good part of this project was our song. We decided to do under the sea, and the xylophone sounded really good! I think we really made Sebastian proud. A not so good part of this project was all the building mishaps. The guitars strings would snap, we couldn't get frets to stay on, our tuner was inaccurate so we'd have to start over, and we had to gather so many identical bottles. When we finally had them all, it was a lot easier. I think this project made me think a lot and grow in my musical understanding!
