A sonar device emits waves of frequency 40 kHz. The wavelength of the wave in water is 0.032 m. Suppose thatthe device is fixed to the bottom of the ship. It emits a signal and the echo from the ocean bed returns 0.8 secondlater. What is the depth of the ocean at that point?
A student standing in a canyon yells "echo" and her voice produces a sound wave of the frequency of f=0.54 kHz. The echo takes t=4.8s to return to the student. Assume the speed of sound through the atmosphere at this location is v=328 m/s
a) what is the wavelength of the soundwave in meters?
b) input the expression for the distance, d, the canyon wall is from the student. (answer should look like 'd='"
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
2.07 m away? The speed of sound is 343 m/s.
Answer in units of s.

- An oceanic depth-sounding vessel sends a sonar of 0.100MHz towards the ocean floor. a) If sound travels at 1520m/s in seawater, what is the wavelength of this signal? b) If the return signal is received 6 seconds later, how deep is the ocean floor?arrow_forwardThe figure shows an air-filled, acoustic interferometer, used to demonstrate the interference of sound waves. Sound source S is an oscillating diaphragm; D is a sound detector, such as the ear or a microphone. Path SBD can be varied in length, but path SAD is fixed. At D, the sound wave coming along path SBD interferes with that coming along path SAD. In one demonstration, the sound intensity at D has a minimum value of 82.0 units at one position of the movable arm and continuously climbs to a maximum value of 1000 units when that arm is shifted by 2.44 cm. Find (a) the frequency of the sound emitted by the source and (b) the ratio of the amplitude at D of the SAD wave to that of the SBD wave. (Take the speed of sound to be 343 m/s.)

An ultrasonic wave from an ultrasound device has a frequency of 2 MHz and is used to image the inside of the body. The resolution limit of the ultrasound device is half the wavelength. Assuming that the human body is mostly water, what is the resolution limit of the ultrasound device? (Answer in mm)arrow_forward

A person is standing 12.0 m away from the wall, equidistant from the loudspeakers. When the person moves 1.00 m parallel to the wall, she experiencesdestructive interference for the first time. What is the frequency of the sound? The speed of sound in air is 343 m/s.arrow_forward
- Determine the minimum distance from the bank that the fisherman (see figure) stands in order that the fish isn't alerted to his presence by hearing his voice travelling through air and then water. Take the man's mouth to be 1.7 m above the ground, take the ground to be at the same level as the water surface, take the speed of sound in air to be 343 m/s and take the speed of sound in this water to be 1430 m/s. 12. punos O 6.8 m O 0.48 m O7.4 m O0.42 m O4.1 m 04.0 marrow_forwardTwo in-phase loudspeakers are placed 6.00 m apart along one wall of a room. They emit sound with a frequency of 512Hz. Starting at the location of one of the loudspeakers, a microphone is moved in a direction perpendicular to the wall until constructive interference is detected for the first time.

The air temperature of the night air is TF=90.00F . Two observers see the flash and hear the bang. The first observer notes the time between the flash and the bang as 1.00 second. The second observer notes the difference as 3.00 seconds. The line of sight between the two observers meet at a right angle as shown below. What is the distance x between the two observers?arrow_forward
- A riverside warehouse has several small doors facing the river. Two of these doors are open as shown in Figure P27.17. The walls of the warehouse are lined with sound-absorbing material. Two people stand at a distance L = 150 in from the wall with the open doors. Person A stands along a line passing through the midpoint between the open doors, and person B stands a distance y = 20 m to his side. A boat o the river sounds its horn. To person A, the sound is loud and clear. To person B, the sound is barely audible. The principal wavelength of the sound waves is 5.00 m. Assuming person B is at the position of the first minimum, determine the distance d between the doors, center to center.arrow_forwardYou are working at an open-air amphitheater, where rock concerts occur regularly. The venue has powerful loudspeakers mounted on 10.6-m-tall columns at various locations surrounding the audience. The loudspeakers emit sound uniformly in all directions. There are ladder steps sticking out from the columns, to help workers service the loudspeakers. Many times, audience members break through the protective fencing around the columns and climb upward on the columns to get a better view of the performers. The upcoming concert is by a group that states that several very-high-volume pulses of sound occur in their concerts, and these sounds are part of their artistic expression. The amphitheater owners are worried about people climbing the columns and being too close to the loudspeakers when these peak sounds are emitted. They do not want to be held responsible for injuries to audience members ears. Based on past performances of the group, you determine that the peak sound level is 150 dB measured 20.0 cm from the speakers on the columns. The owners ask you to determine the heights on the columns at which to mount impassable barricades to keep people from getting too close to the speakers and hearing sound above the threshold of pain.arrow_forwardSound is more effectively transmitted into a stethoscope by direct contact rather than through the air, and it is further intensified by being concentrated on the smaller area of the eardrum. It is reasonable to assume that sound is transmitted into a stethoscope 100 times as effectively compared with transmission though the air. What, then, is the gain in decibels produced by a stethoscope that has a sound gathering area of 15.0 cm2, and concentrates the sound onto two eardrums with a total area of 0.900 cm2 with an efficiency of 40.0% ?arrow_forward
