Problem 71P

Standing Waves in the Human Ear The human ear canal is much like an organ pipe that is closed at one end (at the tympanic membrane or eardrum) and open at the other (Figure 14-37). A typical ear canal has a length of about 2.4 cm. (a) What are the fundamental frequency and wavelength of the ear canal? (b) Find the frequency and wavelength of the ear canal’s third harmonic. (Recall that the third harmonic in this case is the standing wave with the second-lowest frequency.) (c) Suppose a person has an ear canal that is shorter than 2.4 cm. Is the fundamental frequency of that person’s ear canal greater than, less than, or the same as the value found in part (a)? Explain. [Note that the frequencies found in parts (a) and (b) correspond closely to the frequencies of enhanced sensitivity in Figure 14-28.]

2.1.17 The epicenter may or may not be directly above the hypocenter. Seismic waves radiate outward from hypocenter US Array 1. Portable seismic array Faults 1. Normal faults 2. Reverse/thrust faults 3. Strike-slip faults Normal Fault: tensional forces. If we pull something apart Reverse/Thrust Fault: compressions forces. If we push something together Strike-slip Fault : shearing motion. Sliding past one another Stress builds up until rupture occurs at weak point. Australian/Pacific Plate Boundary 1. A lot of earthquakes occur b/c of the amount of faults Fault Rupture 1. We can have a series of events that can occur over long periods of time, but the biggest event is labeled the earthquake. 2. Small events before the earthquake are “foreshocks”
