The musical note "A" creates a sound wave that can be modeled by the function f(x)=sin(880πx)f(x)=sin(880πx), where xx represents the time in seconds. An "A" note completes 440440 cycles of the sine wave per second.What is the length of time for one period of this sine wave?
Microbats use echolocation to navigate and hunt. They emit pulses of high frequency sound waves which reflect off obstacles and objects in their surroundings. By detecting the time delay between the emitted pulse and the return of the reflected pulse, a bat can determine the location of the object. Determine the time delay between the sending of a pulse and the return of its reflection from an object located 12.5 m away. Approximate the speed of the sound waves as 345 m/s.
On a 20°C°C night, a bat hovering in the air emits an ultrasonic chirp that has a
frequency of 45 kHzkHz. It hears an echo 60 msms later.
Suppose the object is an insect flying straight away from the bat. What is the
insect's speed if the ultrasonic echo is shifted down in frequency by 750 Hz?

- An ultrasonic scan uses the echo waves coming from something moving (such as the beating heart of a fetus) inside the body and the waves that are directly received from the transmitter to form a measurable beat frequency. This allows the speed of the internal structure to be isolated and analyzed. The speed of the ultrasound waves in tissue is about 1540 m/s. What is the beat frequency ?beats detected when waves with a frequency of 3.80 MHz are used to scan a fetal heartbeat (moving at a speed of ±8.50 cm/s)? hint that came with it: In this problem there's a stationary source of ultrasound that reflects sound off of a moving object which then returns back to the ultrasound device to measure the frequency. There are 2 Doppler shifts that need to be considered. First the stationary source and the moving observer. Second, when the sound reflects off, the moving object now becomes the source and the ultrasound device becomes the observer. In this shift, the frequency measured by the…arrow_forwardThe frequency of the siren of an ambulance is 900 Hz and is approaching you. You are standing on a corner and observe a frequency of 960 Hz.

An artist in a recording studio turns up the volume of a track so that the intensity of the sound triples. Which is the expression for increase in loudness?

- There was an accident and NASA engineers are trying to sort out where two of their Mars Rovers (named 'Tango' and 'Foxtrot') have landed. The engineers know that landing site A is much hotter than landing site B. Unfortunately, the only working sensors on Tango and Foxtrot measure the speed of sound. If Tango measures the speed of sound at its landing site as 240 m/s, while Foxtrot measures speed of sound as 258 m/s at its landing site, where has each rover landed? Tango landed at site A while Foxtrot landed at site B. Tango landed at site B while Foxtrot landed at site A. Both Tango and Foxtrot landed at site A.
