What instrument emits a sound wave to measure the ocean floor?
sonar
What two pieces of information are needed to map the ocean depth using sonar?
speed and sound waves
Why sound do not have no constant physical properties?
Sound is a matter wave. It's the pressure wave within a matter medium and as such is not fundamental but depends entirely on the medium and the density there. To explain further, since sound is not an object, but is rather a wave transmitted through the vibrations of a medium (such as air or water), each sound's properties are determined not only by the medium through which it is transmitted, but also by the instrument that generated the sound. Further, even for sound waves generated by the same instrument and transmitted through the same medium, the density of the medium will affect the speed of the sound wave and its rate of degradation. For example, the same sound wave generated in the water on the ocean's surface would behave quite differently when generated at a depth of 200 meters beneath the surface, since as the depth increases, the density of the water increases.
Which of these uses sound waves to measure the distance between objects underwater?
Sound waves bounce off the ocean floor and come back up to whatever emitted it. The time it takes for the sound wave to come back tells how far down it went. Doing this many times over and over, one can map out the ocean floor, and if the sound wave comes back relatively fast, that means there is something on the ocean floor.
An instrument used to magnify sound is?
An instrument used to magnify sound
What instrument emits a sound wave to measure the ocean floor?
sonar
What technique uses sound waves to measure the depth of the ocean floor?
Sonar.
What instrument measures uterine depth?
A uterine sound measures uterine depth.
What instrument measures the amplitude of sound on a mobile?
A frequency meter is the instrument that is used to measure the amplitude of sound. It reads the energy from a sound wave.
How do scientist find the depth of the ocean waters?
scientist use sound
How do scientist use sound to find the depth of the ocean?
Scientists know the depth of the ocean by using technology like the Deep Worker or the "Alvin". It takes them to the bottom of the ocean so they can study ocean life. Also ships use sonar (SOund NAvigation and Ranging) to see what the depth of the ocean is.
What instrument uses elctricity to measure sound waves?
oscilloscope
What instrument is used to measure the level of sound in earthquakes?
Seismograph
What instrument uses electricity to measure sound waves?
oscilloscope
How do scientists use sound out to figure out the depth of the ocean?
They use an Echo Sounder. Many pulses of sound per second are sent to the ocean floor & the time it takes to rebound is measured and therefore the depth is calculated.

What type of instrument do you use to measure sound pressure levels?
a Sound Pressure Level Meter is used to measure sound levels.See related link.
