- #7When the sound source is moving relative to the listener, what does not change about the sound wave? The speed. The frequency. The wavelength. Question 17Sound waves travel slower through steel than in air because the molecules in the steel are too close together to transmit the wave. True or false?
- Chapter12-009 Suppose that a sound source is emitting waves uniformly in all directions. If you move to a point twice as far away from the source, the frequency of the sound will be unchanged. half as great. one-fourth as great. twice as great.What is the wavelength in air at 22° C of a 440 Hz sound?Two waves, one traveling in water and another traveling in air, have the same frequency and the same wavelength. The speeds of the two waves are different because they are in different mediums the are the same because they have the same wavelegth and frequency are same in magnitude but opposite in direction because sound has a harder time going through water are impossible to determine without knowing the densities and temperatures of the two mediums.
- Organ pipe Y with an open end in both ends is twice as long as organ pipe X with an open end in one side.What is the ratio of the frequencies between that of organ pipe X and organ pipe Y: A)1:1 B)1:2 C)2:1 D)1:4 E)4:1Chapter12-001 Which of the following is a false statement? Sound waves are longitudinal pressure waves. Sound can travel through a vacuum. Light travels very much faster than sound. The transverse waves on a vibrating string are different from sound waves. "Pitch" (in music) and frequency have approximately the same meaning. O O O O OA geological survey ship mapping the floor of the ocean sends sound pulses down from the surface and measures the time taken for the echo to return. How deep is the ocean at a point where the echo time (down and back) is 3.00 s? The temperature of the seawater is 25.0°C. Speed of the sound in seawater is 1533 m/s (see table 12.1) answer in km
- Dogs can here sound waves with frequencies ranging from 40 Hz to 60 kHz. What are the wavelengths of these frequencies in air (Vs = 340 m/s)?The longitudinal oscillations of air layers in sound wave propogation are consistent with the random thermal movement of molecules in air. Explain.When dolphin swims close to its prey, it transmits sound waves to figure out details(like direction where the fish is moving) of its prey. Now if the frequency of the reflected waves has increased, would the dolphin catch up its prey of fall behind?
