HELP!!! DONT DO THIS JUST FOR POINTS! WILL MARK BRAINLIEST FOR THE BEST ESSAY!
Ultrasound and infrasound are categories of sound with different frequencies. These categories of sound can be used for a variety of different applications. In this research assignment, you will take a look at the industrial applications of ultrasound and infrasound. Your essay should do the following things: • Define and describe in detail (and in your own words) ultrasound and infrasound • Describe how ultrasound and infrasound are used in specific industrial applications and provide detailed examples. When conducting your research, remember to gather information from multiple sources. Start your research by defining ultrasound and infrasound. Then find ideas about industrial applications. The essay should be about 350-450 words, which is 1-1.5 typed pages, double-spaced, using 12-pt. font. Check the rubric to review how you will be graded for this assignment.

Answer:
what type of question it is
Explanation:
Ultrasound are sound waves with frequencies which are higher than those audible to humans (>20,000 Hz). Ultrasonic images, also known as sonograms, are made by sending pulses of ultrasound into tissue using a probe. The ultrasound pulses echo off tissues with different reflection properties and are recorded and displayed as an image.
Infrasound, sometimes referred to as low-frequency sound, describes sound waves with a frequency below the lower limit of audibility (generally 20 Hz). Hearing becomes gradually less sensitive as frequency decreases, so for humans to perceive infrasound, the sound pressure must be sufficiently high. The ear is the primary organ for sensing low sound, but at higher intensities it is possible to feel infrasound vibrations in various parts of the body.
Ultrasound can be used in industry to detect defects in metals. Materials can be tested for internal faults and cracks that could lead to the failure of a structure under certain conditions. Ultrasound imaging provides a quick method of detection and perhaps prevents serious accidents.
Monitoring of infrasound seems to be one of the best ways for detecting atmospheric nuclear tests. As of 2004 there were 24 such monitoring stations out of a projected total of 60. While no nuclear tests have been detected, in 2003 10 stations in the U.S. and Canada monitored the explosion of the space shuttle Columbia. A station in Fairbanks, Alaska detected the explosion of dynamite five miles from the detector. Infrasound detectors are used in Teton Pass, Wyoming to detect the frequent avalanches and send warning signals.
