level questions: Sonar and Ultrasound

QuestionAnswer
Why does Ultrasound work - What are the Simple Processes behind it?-When a Wave hits a Boundary, some of it can be Reflected -If you know the Speed of thee Wave, and then Decide to just Point a Pulse of Sound Waves, and Timing when it comes back, you can find the Distance of the Boundary -Using the Distance = Speed x Time
How can Ultrasound be used for Medical Uses?-Ultrasound can simply Pass through the Body, but some of it can be Reflected back -Knowing the Speed of Ultrasounds, and the Time it took to come Back [And divide that by 2 because you only care for the Distance THERE] you can see the Distance to that Tissue, or Festus -And then the Reflections can be Computerised to make an Image -Examples of Useful images being made is Foetus, Soft Tissues and Organs -And, Ultrasound as of now is Completely Safe
How can Ultrasound be used for Industry Uses?-Flaws in Objects can be Identified because of Ultrasound -When it enters a Pipe, for Example, it will Usually Reflect off the Far Side of it -And it had a Crack, the Waves will be Reflected Sooner and therefore Quicker raising Suspicion
How can Ultrasound be used for Sonar Uses?-Since it travels fairly Fast in Water, and you know the Speed, you can simply Time how Long it Takes to be Picked up Again -When its Picked up again, Half the Time, cause the Timing coming back to you is Irrelevant -This will give you then the Distance to the Sea Bed
