For years, marine scientists were mystified bysound waves detected by underwater microphonesin the Pacific Ocean. These so-calledT waves wereamong the purest sounds in nature. Eventually theresearchers traced the source to underwaterPart Avolcanoes whose rising columns of bubblesresonated like organ pipes. A typical T wave has afrequency of 7 Hz.Knowing that the speed of sound in seawater is 1530 m/s, find the wavelength of a Twave.Express your answer to three significant figures and include the appropriate units.ValueUnitsSubmitRequest AnswerL UO3:48 PM»)(205/3/2020196,

The relationship between the number of decibles B and the intensity I in watts per square meteris denoted by the equation B = 10log(10^12 x I). If the intensity of a given sound is increased by a factor of 100, by how much does the number of decibels increase?
The speed of sound in air is 331 m/s at atmospheric pressure and 0 Celsius. Suppose you put a electronic pinger in an air-tight glass jar and change the pressure of the air inside by a factor 1.3, while the volume, composition and temperature of the air remain the same. What speed would you measure for the sound inside the jar? Give your answer in m/s.
the output power of a spherically symmetric sound source is 6.0 W. the decibel level at a distance d from the source is 88 dB. what is d (in meters)?
A sound wave having a frequency of 345 Hz travels through air at 20 °C. The decibel level at a distance of 16.3 m from the source is measured to be 86.5 dB. What is the maximum displacement of air molecules at that location? Assume the density of air is 1.20 kg/m³ and that the source produces spherical wave fronts. Express the displacement as a number having the units of mirco meters. 1 micro meter = 1 x 10-6 m. For example, If your calculated answer were 1.873 x 107 m, your entry would be the number 0.187

A 38.0-Hz sound wave is barely audible at a sound intensity level of 60.0 dB. The density of air at 20.0°C is 1.20 kg/m3. Speed of sound in air at 20.0°C is 343 m/s. What is the displacement amplitude of a 38.0-Hz sound wave? What is the ratio of the displacement amplitude to the average distance between molecules in air at room temperature, about 3.00 nm?
a medical imaging system sends a soundwave through a piece of bone. the speed of sound through bone is 3500 m/s. if it takes 275 microseconds for the sound wave to make a round trip back and forth across the bone, what is the thickness of the bone?
While sitting next to a road on a calm, warm 27.9ºC evening, you see an ambulance's lights flashing in the distance coming towards you. You hear a frequency of 150 Hz (you have a very keen ear!). However, you know that ambulances have sirens that emit sound at 140 Hz. How fast is the ambulance approaching you, in m/s
Early Doppler shift experiments were conducted using a band playing music on a train. A trumpet player on a moving railroad flatcar plays a 320-Hz note. The sound waves heard by a stationary observer on a train platform hears a frequency of 350 Hz. What is the flatcar’s speed in mph? The temperature of the air is TC = 22°C .
A sound wave arriving at your ear is transferred to the fluid in the cochlea. If the intensity in the fluid is 0.410 times that in air and the frequency is the same as for the wave in air, what will be the ratio of the pressure amplitude of the wave in air to that in the fluid? Approximate the fluid as having the same values of density and speed of sound as water. Speed of sound in dry air (20.0°C, 1.00 atm) is 343 m/s, density of dry air (at STP) is 1.29 kg/m3, density of water is 1000 kg/m3, and speed of sound in water is 1493 m/s.
Two sound waves have intensities of 1 times 10 to the -5 W/m2 and 5 times 10 to the -4 W/m2. What is the difference in their intensities levels (db)? I0 = 10 to the -12 W/m2.
The higher frequency limit for human hearing is 23.9 kHz. If the air temperature is 12.2 °C, the corresponding wavelength (mm; millimeter) of the sound is:
