Doppler effect  Wikipedia
The Doppler effect (or the Doppler shift) is the change in frequency or wavelength of a wave in relation to an observer who is moving relative to the wave source. It is named after the Austrian physicist Christian Doppler, who described the phenomenon in 1842.. A common example of Doppler shift is the change of pitch heard when a vehicle sounding a horn approaches and recedes from an observer.

The Doppler Effect
What is the Doppler Effect? The Doppler effect is observed whenever the source of waves is moving with respect to an observer. The Doppler effect can be described as the effect produced by a moving source of waves in which there is an apparent upward shift in frequency for observers towards whom the source is approaching and an apparent downward shift in frequency for observers from whom the ...
Relativistic Doppler effect  Wikipedia
The relativistic Doppler effect is the change in frequency (and wavelength) of light, caused by the relative motion of the source and the observer (as in the classical Doppler effect), when taking into account effects described by the special theory of relativity.. The relativistic Doppler effect is different from the nonrelativistic Doppler effect as the equations include the time dilation ...
Doppler Effect  Astronomy Notes
Formulae. Wavelength shift: = new  rest. rest is the wavelength measured if the object is at rest and new is the wavelength measured for the moving object.; Doppler effect: = rest × V radial /c, where V radial is the object's speed along the line of sight and c is the speed of light. If new > rest, the object is moving away (redshift).; If new < rest, the object is approaching (blueshift).
Doppler Effect  Definition of Doppler Effect by Merriam ...
: a change in the frequency with which waves (as sound, light, or radio waves) from a given source reach an observer when the source and the observer are in motion with respect to each other so that the frequency increases or decreases according to the speed at which the distance is decreasing or increasing — compare shift sense a

The Doppler Effect in Light Waves So far the Doppler effect has been discussed purely in terms of sound waves; but Doppler himself maintained that it could be applied to light waves as well, and experimentation conducted in 1901 proved him correct.
The Doppler Effect and Shock Waves  physicsclassroom.com
The Doppler effect is a phenomenon observed whenever the source of waves is moving with respect to an observer. The Doppler effect can be described as the effect produced by a moving source of waves in which there is an apparent upward shift in frequency for the observer and the source are approaching and an apparent downward shift in frequency when the observer and the source is receding.

Dopplereffect  Wikipedia
Ontdekking. Het effect werd genoemd naar de Oostenrijkse natuurkundige Christian Doppler, die in 1842 dit verschijnsel voor zowel licht als geluidsgolven beschreef (Über das farbige Licht der Doppelsterne und einiger anderer Gestirne des Himmels).In 1845 werd het experimenteel getoetst door de Nederlandse meteoroloog Christophorus Buys Ballot.Hij deed dat door een groep hoornisten bij ...
