(i just need someone to double check it for me, and see if it's right. tell me if i should add anything ^^ )
assignment: ultrasound and infrasound research exploration
ultrasound and infrasound are categories of sound with different frequencies. these categories can be used for a variety of different purposes. for example, ultrasound is used to diagnose and treat injuries in the medical field. in this research assignment, you will look at the industrial applications of both categories of sound.
your essay should address 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 of both.
when conducting your research, remember to gather information from multiple sources. start your research by defining ultrasound and infrasound. then look for how ultrasound and infrasound are used in industrial applications.

( my definition of ultrasound and infrasound)
ultrasound: an ultrasound is a high-frequency sound wave. its frequently used to analyze the fetus throughout pregnancy.
infrasound: a infrasound is a low-frequency sound wave. it's generally used toward long-distance communication. various animals can detect infrasound.
( description of how ultrasound and infrasound are used )
ultrasound is regularly applied to medical cases in pregnancy. or in some cases, it's simply used to examine your organs, vessels, and tissues without requiring an incision. infrasound is regularly applied to long-distance communication. humans remain incapable of hearing infrasound although animals like whales, alligators, cuttlefish, elephants can.
also if you could give me 5 sources i could use on my essay for ultrasound and infrasound, that would be great. ^^
