(a) Seismographs measure the arrival times of earthquakes with a precision of 0.100 s. To get the distance to the epicenter of the quake, geologists compare the arrival times of S- and P-waves, which travel at different speeds. If S- and P-waves travel at 4.00 and 7.20 km/s, respectively, in the region considered, how precisely can the distance to the source of the earthquake be determined? (b) Seismic waves from underground detonations of nuclear bombs can be used to locate the test site and detect violations of test bans. Discuss whether your answer to (a) implies a serious limit to such detection. (Note also that the uncertainty is greater if there is an uncertainty in the propagation speeds of the S- and P-waves.)

A bat flying at 4.65 m/s is chasing an insect flying in the same direction. The bat emits a 39.9-kHz chirp and receives back an echo at 40.6 kHz. (Take the speed of sound in air to be v = 343 m/s.) (a) What is the speed of the insect? m/s(b) Will the bat be able to catch the insect? YesNo Explain.
A bat flying along in a cave at a velocity of Vbat = 4.52 m/s sends out a sound wave of femitted = 59800 Hz. The sound wave reflects off of a stationary stalactite and the bat hears a different frequency than the one he emitted. Use V sound = 346.4 m/s throughout this problem. What frequency strikes the stalactite? fstalactite = Hz The stalactite reflects what strikes it (NOT the original pitch). What frequency does the bat then hear coming from the stalactite? fbat What is the frequency of beats heard by the bat? fbeat Hz NOTE: The bat hears two things: ● Vbat ● The original frequency emitted. The "double doppler shifted" note from the stalactite. = = Hz
You are moving away from a stationary source of sound and hear a frequency that is 0.5 % lower than the rest frame frequency. Taking the speed of sound in air as 343 m/s, calculate your speed of movement?

You are standing on a train station platform as a train goes by close to you. As the train approaches, you hear the whistle sound at a frequency of f1 = 93 Hz. As the train recedes, you hear the whistle sound at a frequency of f2 = 79 Hz. Take the speed of sound in air to be v = 340 m/s. Find an equation for the speed of the sound source vs, in this case it is the speed of the train. Express your answer in terms of f1, f2, and v. Find the numeric value, in meters per second, for the speed of the train. Find an equation for the frequency of the train whistle fs ("s" is for "source") that you would hear if the train were not moving. Express your answer in terms of f1, f2, and v. Find the numeric value, in hertz, for the frequency of the train whistle fs that you would hear if the train were not moving.
