HowUltrasonicTechnologyWorks:

Ultrasonictechnologyusessoundwavesatafrequencyabovetherangeofhumanhearing,typicallybetween20kHzand1MHz.Thesesoundwavesareproducedbyatransducer,whichconvertselectricalenergyintomechanicalvibrations.Thevibrationscreatesoundwavesthattravelthroughamedium,suchasairorwater,andbounceoffofobjectsorsurfacestheyencounter.Whenthesoundwavesreturntothetransducer,theyareconvertedbackintoelectricalsignalsthatcanbeprocessedtocreateanimageormeasurement.

Ultrasonictechnologycanalsobeusedtocreateaprocesscalledcavitation,whichinvolvesthecreationofmicroscopicbubblesinaliquid.Thesebubblesarecreatedbythehigh-frequencysoundwavesandcanimplodewithgreatforce,creatingintenselocalizedheatandpressure.Thisprocessisusedinvariousindustrialapplicationsrangingfromcleaninganddegreasingtoweldingandcutting.
