The frequency of a wave measures the number of times a complete wave cycle will pass a given position. Angular frequency is similar, except that it's been converted to a form that's easier to use in trigonometric equations. While frequency measures cycles per second, or Hertz, angular frequency meas
The design of a hot-air balloon allows you to use any lightweight material, including tissue paper, to form the balloon. A properly formed tissue-paper balloon will fly while handling a surprising amount of weight. Start small, creating simple balloons for your first try and then invest in larger ba

Scientists use a variety of instruments to measure earthquakes, or seismic activity. One type of instrument is the geophone. Like any electronic instrument, geophones are designed with differing frequency sensitivities, sometimes requiring a microphone amplifier.
Cobra radios provide a method of long-range communication through the UHF frequencies. These radios use simple controls to switch frequencies and control the squelch on the band. Tuning into different frequencies is as easy as pushing a button and looking at the display.
