Big Bang Gizmos-Doppler Shift Already Passed

Doppler shift {Ans: Radar gun is a device that uses the ___________________ to measure the speed of a moving object.}waves {Ans: Sound _________________ cause our eardrums to vibrate. The vibrations are transmitted to the auditory nerves via a series of delicate structures in the inner ear.}compressed {Ans: Just as a ship leaves a visible wake in the water behind it, a supersonic jet leaves behind an invisible "wake" of __________________ sound waves.}transverse/light {Ans: The wavelength of a ________________ wave is the distance between consecutive crests OR troughs.}pressure {Ans: Sound energy causes air molecules to vibrate back and forth in the same direction that the sound is moving. This creates the alternating high- and low-___________________ areas.}wavelength(s) {Ans: The shorter the ________________________ of a wave is, the greater its frequency. Longer ______________________ correspond to lower frequencies.}
