wave length/wavelength — The distance traveled in one period or one cycle by a periodic disturbance. It is the distance between repeating units of a wave pattern. It is commonly designated by the Greek letter lambda (Λ). In a sine wave, the wavelength is the distance… … Aviation dictionary

Frequency spectrum — Familiar concepts associated with a frequency are colors, musical notes, radio/TV channels, and even the regular rotation of the earth. A source of light can have many colors mixed together and in different amounts (intensities). A rainbow, or… … Wikipedia
Wave function — Not to be confused with the related concept of the Wave equation Some trajectories of a harmonic oscillator (a ball attached to a spring) in classical mechanics (A B) and quantum mechanics (C H). In quantum mechanics (C H), the ball has a wave… … Wikipedia
Frequency — F/A/V The number of times a signal vibrates each second as expressed in cycles per second (cps) or Hertz (Hz). (Sound) A&V The number of complete cycles of a periodic waveform that occur in a given length of time. Usually specified in cycles per… … Audio and video glossary
