Yeah, well today... err, I mean yesterday we went over the answers of the lesson 15 vocabulary thingy. Answers below:
1) Amplitude
2) Frequency
3) Interference
4) Wavelength
5) Standing Wave
6) Sound Level
7) Opening-Pipe Resonator
8) Octave
9) Resonance
10) Consonance
11) Loudness
12) Dissonance
13) Timbre
14) Doppler Shift
15) Closed-End Pipe Resonator
16) Fundamental
17) Beat
18) Pitch
19) Harmonics
20) Echoes
21) Decibels
Well, when we finished this we went onto an experiment. We tested the sounds a closed pipe resonator with a tuning fork. To see what sounds it would make when we shifted it up and down a tube full of water. We were testing in which area where you would be able to hear the air compressing and rarefacting. We had 2 kinds of experiments: one of them in cold water and the other in hot water and in all the labs we do theres a lab work sheet that we had to do.
Oh yeah, we read pages 6 - 9 or something like that in the yellow book. The book talks about standing wave patterns in longitudinal waves. I shows where the antinodes and nodes are. We also read about Standing Waves with an open-tube resonator and standing waves with a closed-tube resonator.
Well thats the end of my post the next scribe was total random (not really since i just picked the first one) jeamille. Good luck with that.
