Document Summary
Where you should be by now: done: everything from weeks 1-3. Experiment 1: be working on week 4: Frequency, wave concepts: experiments = most important part of learning, books + software: johnston, audacity, raven, get a microphone if you don"t have one. Topics for tonight: experiment 1 discussion of what was learned, terminology + concepts part 3, pitch vs. Frequency + music stuff: a look ahead: experiment 2, assignments. Sound is : a longitudinal wave, source medium receiver, wave form graph shows increase and decrease in pressure (air particles) Compression (high pressure) and rarefaction (low pressure: source vibration moves against and away from the air, wave form graph shows distance vs. pressure (distance btwn source and receiver) Not plotting time b/c lined up w/ diagram showing distance. A wave form graph does show time, but this example does not. Experiment 1: performance: avg. score of 76-91% If having issues, talk to dr. ottsen or justin to work them out.
