A certain instant camera determines the dis- tance to the subject by sending out a sound wave and measuring the time needed for the wave echo to return to the camera. How long would it take the sound wave to return to the camera if the subject were 7 . 59 m away? The speed of sound is 343 m / s. Answer in units of s

Bats use sound to sense objects by sending out short ultrasound pulses and listening for the echo off the object. A. Sketch the ultrasound pulse leaving the bat, reflecting off the object and returning to the bat. B. If a stationary bat is 43 m from an object, how much time elapses between when the bat emits the pulse and it hears the echo? Assume the standard speed of sounds. C. If the object were moving toward the bat, would...

A rescue plane flies horizontally at a constant speed searching for a disabled boat. When the plane is directly above the boat, the boat's crew blows a loud horn. By the time the plane's sound detector perceives the horn's sound, the plane has traveled a distance equal to two-thirds its altitude above the ocean. (a) If it takes the sound 2.10 s to reach the plane, determine the speed of the plane. Take the speed of sound to be 343...

3. Sound waves can be used to map the sea floor by timing how long it takes the echo to reach the surface of the water. A certain mapping ship uses 600 kHz ultrasound. A. What is the wavelength of the sound in the air and in the water? B. Sketch the ship sending out a pulse, the pulse bouncing off the sea floor, and returning to the ship. C. If the echo reaches the detector 0.52 s after the...

As a certain sound wave travels through the air, it produces pressure variations (above and below atmospheric pressure) given by ΔP = 1.18 sin(πx - 332πt) in SI units. (Note: Use the following values as needed, unless otherwise specified. The equilibrium density of air is ρ = 1.20 kg/m3. Pressure variations ΔP are measured relative to atmospheric pressure, 1.013 105 Pa.) (a) Find the amplitude of the pressure variations. Pa (b) Find the frequency of the sound wave. Hz (c)...

For testing purposes, a musical instrument manufacturing company creates a device so that when you blow into one end with your instrument, sound comes out the other end in opposite directions. A sound technician uses a whistle and generates sound waves with a frequency of 226 Hz. The waves travel in opposite directions in a sound studio, are reflected by end walls, and return. The studio is 42.0 m long and the whistle is located 14.0 m from one end....
