PHYS 305 Lecture Notes - Lecture 6: Wave Height, Plastic Bottle, Neutral Axis
Document Summary
Amplitude vs. wave height: amplitude is measurement from neutral axis to peak positive/ pressure, wave height is from peak to trough (maximum wave height) 2x the amplitude. Ocean waves: gradual change in water depth > refraction. Waves come in at an angle and become more and more parallel to shore as they approach it. Acura example: sound control not just insulation, active sound control. Speakers to send opposing frequencies : sound cancellation (like in exp. Honda example: cut grooves in asphalt to play a tune while driving over the road. Hitting more grooves per second (less distance between grooves) will increase pitch. Topics for tonight: waveform, experiment 2 synthesis, experiment 3 analysis, raven demo, significant digits and accuracy, assignments instructions 7. Parts 1 and 2: synthesis is: the combining of two or more entities to form something new (wikipedia, fourier"s theorem: any periodic waveform can be produced from sine waves with.
