(a) What is the speed of sound in a medium where a 100kHz frequency produces a 5.96cm wavelength? (b) Which substance in Table 17.1 is this likely to be?
To measure her speed, a skydiver carries a buzzer emitting a steady tone at 1 800 Hz. A friend on the ground at the landing site directly below listens to the amplified sound he receives. Assume the air is calm and the speed of sound is independent of altitude. While the skydiver is falling at terminal speed, her friend on the ground receives waves of frequency 2 150 Hz. (a) What is the skydivers speed of descent? (b) What If? Suppose the skydiver can hear the sound of the buzzer reflected from the ground. What frequency does she receive?

An airplane moves at Mach 1.2 and produces a shock wave. (a) What is the speed of the plane in meters per second? (b) What is the angle that the shock wave moves?
The auditory canal of the human ear extends about 2.5 cm from the outer ear to the eardrum.a) Explain why the human ear is especially sensitive to sounds with frequencies close to 3500 Hz. Use v = 344m / s. b) Would you expect the ear to be especially sensitive to frequencies near 7000 Hz?At 10,500 Hz? Why?
Microwaves travel at the speed of light, 3.00 ✕ 108 m/s. When the frequency of microwaves is 7.00 ✕ 109 Hz, what is their wavelength? m
Under favorable conditions, the human eye can detect light waves with intensities as low as 2.50 x 10-1² W/m². At this intensity, what is the average power incident on a pupil of diameter 8.10 mm? W If this light is produced by an isotropic source 11.6 m away, what is the average power emitted by the source
An echocardiogram can measure the Doppler shift of the sound reflected from flowing blood. A sound wave of 5 MHz is used to image the heart and a shift of 100 Hz is detected from a region of flowing blood. What is the blood's speed? [Note: The speed of sound in heart tissue is about 1500 m/s.] *Clarification: The frequency is shifting up. That is, the new fewquency is (5MHZ + 100 Hz).
hw 3 A sound wave strikes a student’s eardrum with a power of 28 μW. The sound’s intensity at the eardrum is 0.76 W/m2. Assuming a circular eardrum, what is the radius of the student’s eardrum, in millimeters? The same sound wave delivers the same power to the eardrum of a second student. His eardrum has a 19 % larger radius than that of the first student. What is the intensity of the sound, in watts per square meter, at the second student’s eardrum?
AM radio signals are broadcast at frequencies between 550 kHz (kilohertz) and 1600 kHz and travel at 3 x 10^8 m/s. a) What is the range of wavelengths for those signals? b) FM frequencies range between 88 MHz (megahertz) and 108 MHz and travel at the same speed. What is the wavelength range of the FM frequencies.
