Show that the speed of sound in 20.0°C air is 343 m/s, as claimed in the text.
A piano tuner uses a 512-Hz tuning fork to tune a piano. He strikes the fork and hits a key on the piano and hears a beat frequency of 5 Hz. He tightens the string of the piano, and repeats the procedure. Once again he hears a beat frequency of 5 Hz. What happened?
A sound wave produced by an ultrasonic transducer, moving in air, is modeled with the wave equation s(x,t)=4.50nmcos(9.15104m1x2(5.00MHz)t) . The transducer is to be used in nondestructive testing to test for fractures in steel beams. The speed of sound in the steel beam is v=5950 m/s. Find the wave function for the sound wave in the steel beam.
How can an object move with respect to an observer so that the sound from it is not shifted in frequency?
A stone is dropped from rest into a well. The sound of the splash is heard exactly 2.00 s later. Find the depth of the well if the air temperature is 10.0C.
Early Doppler shift experiments were conducted using a band playing music on a train. A trumpet player on a moving railroad flatcar plays a 320-Hz note. The sound waves heard by a stationary observer on a train platform hears a frequency of 350 Hz. What is the flatcar’s speed in mph? The temperature of the air is TC=22C .
Calculate the speed of sound on a day when a 1500-Hz frequency has a wavelength of 0.221 m.
The ear canal resonates like a tube closed at one end. (See [link]Figure 17_03_HumEar[/link].) If ear canals range in length from 1.80 to 2.60 cm in an average population, what is the range of fundamental resonant frequencies? Take air temperature to be 37.0°C, which is the same as body temperature.
Is the Doppler shift real or just a sensory illusion?
Ultrasonic sound waves are often used in methods of nondestructive testing. For example, this method can be used to find structural faults in a steel I-beams used in building. Consider a 10.00 meter long, steel I-beam with a cross-section shown below. The weight of the I-beam is 3846.50 N. What would be the speed of sound through in the I-beam? (Ysteel=200GPa,steel=159GPa) .
