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

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...
Problem 15.28 Review Constants Periodic Table Part A Research vessels at sea can create images of their surroundings by sending out sound waves and measuring the time until they detect echoos. The image of a shipwreck on the ocean bottom shown in (Figure 1) was made from the surface with 600 kHa utrasound What was the wavelength? Use values given in (Figure 2) i# necessary Express your answer with the appropriate units Figure K2 of2 X- 1 Value Units The...
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....
PHET Sound Simulation Purpose - To explore sound (a longitudinal wave) and how it can be modeled as a transverse wave Obtain com puter with PHET software on it. Get headphones if possible and plug into sound port. Open PHET simulations and find Sound and Waves simulations. Open the simulation called "Sound". There are 5 tabs. Listen to a Measure Two Source Interference Listen with Interference by Reflection Varying Air Pressure Single Source Open the one called listen to a...
Apps Problems Return to Blackboard Halliday, Fundamentals of Physics, 10e Help I Sy PRINTER VERSION BACK NEXT Question 5 The water level in a vertical glass tube 1.00 m long can be adjusted to any position in the tube. A tuning fork vibrating at 717 Hz is held just over the open top end of the tube, to set up a standing wave of sound in the air-filled top portion of the tube. (That air-filled top portion acts as a...
Please give detailed explanations/solutions, thank you! [5] 4. (a) Write a brief essay on standing waves on stringed musical instruments as compared to standing waves on the pipes of a pipe organ having pipes that are open at both ends as well as pipes that are open at one end and closed at the other. (b) You have been asked to determine the length of a metal tube that has been bent into a complex shape. One end of the...
I am completing a study guide for the next section of class because I am trying to get ahead. Any suggestions? A wave whose displacement velocity is either in the same direction or opposite direction as the wave velocity describes which type of a wave? a. Transverse wave b. Mechanical wave c. Longitudinal wave d. Electromagnetic wave Which of the following are always one wavelength apart and are drawn as parallel lines? Plane waves b. Wave fronts c. Wave phase...
question 4-7 4. Travelling Waves and Their Characteristics A rope wave travels in the positive x -direction. You are also told that the speed of the wave is 1000 cm/s, its frequency is 200 Hz, and that the wave is subject to the following initial conditions: at x 0 and t = 0: y =-1 cm, and, at x = 0 and t : ar = +20 cm/s (this is the velocity of the point on the rope at horizontal...
