Radio frequency is used for radio communication technology, wireless networks and telecommunication systems. As of 2011, they sell for about $400 used over eBay, where they appear about once a month. When those waves bounce off an object, they return to the ultrasound equipment, which translates the waves into an image. It is found that when pressure or compression is applied on two opposite faces of a quartz crystal, then charges are produced on a set of opposite faces which are perpendicular to the faces at which pressure is applied. In the video below, a tone slowly rises from a superlow 20-hertz tone to a 1,000-times-higher 20 kilohertz. It’s found in the Schumann Resonance, which runs somewhere between 3 and 60 Hz to create the lightning that strikes the Earth. Sweeping Pink, White and Grey Noise has.
