How do sound vibrations of atoms differ from thermal motion?
Jack and Jill go for a walk along an abandoned railroad track. Jack puts one ear next to a rail, while Jill, 200 m away, taps on the rail with a stone (Figure 6.55). How much sooner does Jack hear the sound through the steel rail than through the air?
What is the minimum speed at which a source must travel toward you for you to be able to hear that its frequency is Doppler shifted? Thai is, what speed produces a shift of 0.300% on a day when the speed of sound is 331 m/s?
A sound wave propagates in air at 27C with frequency 4.00 kHz. It passes through a region where the temperature gradually changes and then moves through air at 0C. Give numerical answers to the following questions to the extent possible and state your reasoning about what happens to the wave physically. (a) What happens to the speed of the wave? (b) What happens to its frequency? (c) What happens to its wavelength?
A tuning fork generates sound waves with a frequency of 246 Hz. The waves travel in opposite directions along a hallway, are reflected by end walls, and return. The hallway is 47.0 m long and the tuning fork is located 14.0 m from one end. What is the phase difference between the reflected waves when they meet at the tuning fork? The speed of sound in air is 343 m/s.
When sound passes from one medium to another where its propagation speed is different, does its frequency or wavelength change? Explain your answer briefly.
(a) Ear trumpets were never very common, but they did aid people with hearing losses by gathering sound over a large area and concentrating it on the smaller area of the eardrum. What decibel increase does an ear trumpet produce it its sound gathering area is 900 cm2 and the area of the eardrum is 0.500 cm2, but the trumpet only has an eficiency of 5.00% in transmitting the sound to the eardrum? (b) Comment on the usefulness of the decibel increase found in part (a).
Is the Doppler shift real or just a sensory illusion?
How can an object move with respect to an observer so that the sound from it is not shifted in frequency?
A 0.80-m-long tube is opened at both ends. The air temperature is 26°C. The air in the tube is oscillated using a speaker attached to a signal generator. What are the wavelengths and frequencies of first two modes of sound waves that resonate in the tube?
A cowboy stands on horizontal ground between two parallel, vertical clifTs. He is not midway between the cliffs. Me fires a shot and hears its echoes. The second echo arrives 1.92 s after the first and 1.47 s before the third. Consider only the sound traveling parallel to the ground and reflecting from the cliffs, (a) What is the distance between the cliffs? (b) What If? If he can hear a fourth echo, how long after the third echo does it arrive?
Older auto-focus cameras sent out a pulse of sound and measured the time interval required for the pulse to reach an object, reflect off of it, and return to be detected. Can air temperature affect the cameras focus? New cameras use a more reliable infrared system.
