Doppler effect |
Also found in: Dictionary/thesaurus, Medical, Legal, Encyclopedia, Wikipedia | 0.18 sec. |
Doppler effectChange in the observed frequency (or wavelength) of waves due to relative motion between the wave source and the observer. The Doppler effect is responsible for the perceived change in pitch of a siren as it approaches and then recedes, and for the red shift of light from distant galaxies. It is named after the Austrian physicist Christian Doppler. How to thank TFD for its existence?

| Doppler toppler After 60 years of anticipation, experimenters finally created an inverse Doppler effect, an increase in the frequency of an electromagnetic wave, rather than the usually observed decrease in frequency, from a receding source (164: 358). Precipitation moving toward the radar causes the electromagnetic waves to bounce back with higher frequency--it's called the Doppler effect. To the right of these two works hung Tomaselli's Doppler Effect in Blue, 2002, with its swirling strings of collaged eyes, ears, mouths, hands, feet, flowers, birds, and insects, all interspersed with actual pills. |
