Christian Johann Doppler And The Doppler Effect Austrian physicist christian Johann doppler (18031853) discovered that a wave sfrequency changes when the source and observer are in motion relative to http://www.usefultrivia.com/science_trivia/science_trivia_005a.html
Extractions: That's right! Austrian physicist Christian Johann Doppler (1803-1853) discovered that a wave's frequency changes when the source and observer are in motion relative to one another. This is known as the Doppler effect. Back to Science Trivia Index RELATED LINKS Art Trivia Bible Trivia Celebrity Trivia Comic Book Trivia ... Links .com

Extractions: The sudden change in pitch of a car horn as a car passes by (source motion) or in the pitch of a boom box on the sidewalk as you drive by in your car (observer motion) was first explained in 1842 by Christian Doppler. His Doppler Effect is the shift in frequency and wavelength of waves which results from a source moving with respect to the medium, a receiver moving with respect to the medium, or even a moving medium. The perceived frequency ( f f ) and the relative speeds of the source ( v s ), observer ( v o ), and the speed ( v ) of waves in the medium by The choice of using the plus (+) or minus (-) sign is made according to the convention that if the source and observer are moving towards each other the perceived frequency ( f higher than the actual frequency ( f ). Likewise, if the source and observer are moving away from each other the perceived frequency ( f lower than the actual frequency ( f Although first discovered for sound waves, the Doppler effect holds true for all types of waves including light (and other electromagnetic waves). The Doppler effect for light waves is usually described in terms of colors rather than frequency. A red shift occurs when the source and observer are moving away from eachother, and a blue shift occurs when the source and observer are moving towards eachother. The red shift of light from remote galaxies is proof that the universe is expanding. The animations below will illustrate this phenomena for a moving source and stationary observer.
Doppler Effect Originally discovered by the Austrian mathematician and physicist, ChristianDoppler (180353), this change in pitch results from a shift in the frequency http://archive.ncsa.uiuc.edu/Cyberia/Bima/doppler.html
Extractions: Back Up Map Glossary ... Information Heard an ambulance go by recently? Remember how the siren's pitch changed as the vehicle raced towards, then away from you? First the pitch became higher, then lower. Originally discovered by the Austrian mathematician and physicist, Christian Doppler (1803-53), this change in pitch results from a shift in the frequency of the sound waves, as illustrated in the following picture. As the ambulance approaches, the sound waves from its siren are compressed towards the observer. The intervals between waves diminish, which translates into an increase in frequency or pitch. As the ambulance recedes, the sound waves are stretched relative to the observer, causing the siren's pitch to decrease. By the change in pitch of the siren, you can determine if the ambulance is coming nearer or speeding away. If you could measure the rate of change of pitch, you could also estimate the ambulance's speed. By analogy, the electromagnetic radiation emitted by a moving object also exhibits the Doppler effect. The radiation emitted by an object moving toward an observer is squeezed; its frequency appears to increase and is therefore said to be blueshifted . In contrast, the radiation emitted by an object moving away is stretched or
