Question: Ultrasound is the name given to frequencies above the human range of hearing, which is about 20000 Hz. Waves above this frequency, can be used to penetrate the body and to produce images by reflecting from surfaces. In a typical ultrasound scan, the waves travel with a speed of 1500 m/s. For a good detailed image, the wavelength should be no more than 1.0 mm.
Part A: What frequency is required?
I'm having problems with this question. Please, show me the process of solution. Thanks!
