A human cannot hear sound at a frequency of 100 kHz or sound at 102 kHz. But if you into a room in which two sources are emitting sound waves, one at 100 kHz and the other at 102 kHz, you'll hear sound. Why? Explain
Sound waves sent by a dolphin travel with a speed of 1500 m/s in water. A dolphin emits sound wave directed toward the ocean floor below. If the sound wave takes 0.2 seconds to reach it, how far is the ocean floor
from the dolphin?

- A human cannot hear sound at a frequency of 100 kHz or sound at 102 kHz. But if you walk into a room in which two sources are emitting sound waves, one at 100 kHz and the other at 102 kHz, you’ll hear sound. Explain.arrow_forwardA bat can detect small objects, such as an insect, whose size is approximately equal to one wavelength of the sound the bat makes.

- •15 O E A handclap on stage in an amphitheater sends out sound waves that scatter from terraces of width w = 0.75 m (Fig. 17-33). The sound returns to the stage as a periodic series of pulses, one from each terrace; the parade of pulses sounds like a played note. (a) Assuming that all the rays in Fig. 17-33 are horizontal, find the frequency at which the pulses return (that is, the frequency of the perceived note). (b) If the width w of the terraces were smaller, would the frequency be higher or lower? Terrace Figure 17-33 Problem 15.arrow_forwardGood day, Maam/Sir. I hope you can help me to my study.

- 2) You want to perform an underwater speed of sound experiment (similar to that done today) to check the speed of sound in water at a swimming pool. You know this speed to be approximately 1500 m/s. You will tap one wall under water on one side of the pool with a hammer and record with an underwater microphone at the opposite wall 25 m away. 2a) What is the duration of each reflection interval (how long it takes for the sound pulse to go 1 roundtrip? 2b) If you want to capture about 100 data points within each reflection interval, what sampling rate should you use in terms of samples/second? 2c) If you want to capture about 100 data points within each reflection interval, what sampling rate should you use in terms of seconds/sample?arrow_forwardUltrasonic diagnostics may be used to locate a tumor in an organ such as the liver. The figure shows a beam of ultrasonic waves that enter the surrounding medium, refract into the liver, reflect off the tumor, and refract back into the surrounding medium. If the speed of the wave as it travels through the liver is 4.1% less than when it is traveling through the surrounding medium, determine the depth of the tumor. cmarrow_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_forward
- Loudspeakers can produce intense sounds with surprisingly small energy input in spite of their low efficiencies. Calculate the power input needed to produce a 90.0-dB sound intensity level for a 12.0-cm-diameter speaker that has an efficiency of 1.00% . (This value is the sound intensity level right at the speaker.)arrow_forwardAn ultrasonic tape measure uses frequencies above 20 MHz to determine dimensions of structures such as buildings. It does so by emitting a pulse of ultrasound into air and then measuring the time interval for an echo to return from a reflecting surface whose distance away is to be measured. The distance is displayed as a digital readout. For a tape measure that emits a pulse of ultrasound with a frequency of 22.0 MHz., (a) what is the distance to an object from which the echo pulse returns after 24.0 ms when the air temperature is 26C? (b) What should be the duration of the emitted pulse if it is to include ten cycles of the ultrasonic wave? (c) What is the spatial length of such a pulse?arrow_forwardIs it possible to create a situation in which there is only destructive interference? Explain.arrow_forward
