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 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?

A bat flying at 5.00 m/s is chasing an insect flying in the same direction. The bat emits a 40.0 kHz chirp and receives back an echo at 40.4 kHz. Assume the speed of sound is 343 m/s. 1. What is the equation for doppler shift? 2. If you were calculating the frequency of the chirp observed by the insect, what would the value of fs be? 3. For question 2, would vo represent the velocity of the bat or the insect? Does the motion of the insect increase or decrease the frequency observed by the insect? Would vo be positive or negative? 4. For question 2, would vs represent the velocity of the bat or the insect? Would vs be positive or negative? 5. Write the doppler shift equation to find the frequency of the chirp observed by the insect. Use fi for the frequency observed by the insect and vi for the velocity of the insect. (Do not solve this equation yet.) 6. If you were calculating the frequency of the chirp observed by the bat, what would the value of f0 be? 7. For question 6, what would…
