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?
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?
You are driving toward the base of a cliff and you honk your horn. (a) Is there a Doppler shift of the sound when you hear the echo? If so, is it like a moving source or moving observer? (b) What if the reflection occurs not from a cliff, but from the forward edge of a huge alien spacecraft moving toward you as you drive?
How can an object move with respect to an observer so that the sound from it is not shifted in frequency?
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?
When sound passes from one medium to another where its propagation speed is different, does its frequency or wavelength change? Explain your answer briefly.
What is the wavelength of the waves you create in a swimming pool if you splash your hand at a rate of 2.00 Hz and the waves propagate at 0.800m/s ?
A sound wave traveling in 20°C air has a pressure amplitude of 0.5 Pa. What is the intensity of the wave?
Air temperature in the Sahara Desert can reach 56.0°C (about 134°F). What is line speed of sound in air at that temperature?
. The frequency of middle C on the piano is 261.6 Hz. (a) What is the wavelength of sound with this frequency as it travels in air at room temperature? (b) What is the wavelength of sound with this frequency in water?
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.
How do sound vibrations of atoms differ from thermal motion?
