text: The Doppler effect (or the Doppler shift) is the change in frequency of a wave in relation to an observer who is moving relative to the wave source.
text: Doppler effect is a change in frequency and wavelength of a wave.
text: First explained in 1842 by Christian Doppler, the 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.
text: That was the Doppler effect - a shift in the apparent frequency for a sound wave produced by a moving source.
text: Doppler Shift is the change in the frequency of a wave for an observer if the observer is moving relative to the source of the wave.
text: Doppler effect is the change in frequency of a wave for an observer moving relative to its source.
text: So basically Doppler Effect is the change in frequency or wavelength due to the relative motion between source and observer.
text: The Doppler effect is the change in the observed frequency of a wave when the source or the detector moves relative to the transmitting medium.
text: The Doppler effect (or Doppler shift), named after Austrian physicist Christian Doppler who proposed it in 1842 in Prague, is the change in frequency of a wave for an observer moving relative to the source of the wave.

text: The Doppler Effect is the change in frequency of a wave for an observer due to the motion of the source.
text: The Doppler Effect is the change in the observed wavelength or frequency of a waveform, as compared with that emitted from the source, when the source and/or observer are moving with respect to the wave medium.
text: The Doppler effect, named after Christian Doppler, is the change in frequency and wavelength of a wave as perceived by an observer moving relative to the source of the waves.
text: The Doppler effect is the change in frequency of a wave for an observer moving relative to the source of the wave.
text: The Doppler effect (or the Doppler shift) is the change in frequency or wavelength of a wave for an observer who is moving relative to the wave source.
text: The Doppler effect (or Doppler shift) is the change in frequency and wavelength of a wave for an observer moving relative to the source of the waves.
text: The Doppler Effect for sound is the change in pitch or frequency that you hear when the source of sound is moving with respect to you.
text: In astronomy, the Doppler effect is the change in wavelength of light caused by movement of a light source such as a star or a whole galaxy.
text: The Doppler effect is the change in the observed frequency of a wave when the source or the detector moves relative to the transmitting medium.
text: Doppler effect is a change in frequency and wavelength of a wave.
text: The Doppler effect, named for Austrian mathematician Christian Doppler, is a change in sound frequency (or the frequency of any wave, for that matter) caused because the source emitting the sound (or the observer) moves in the time between the emission of each successive wave front.
text: Doppler effect is a change in frequency and wavelength of a wave.
text: Doppler effect is a change in frequency and wavelength of a wave.
text: The Doppler effect is a change in the observed pitch of a sound, due to relative motion between the source and the observer.
text: The Doppler effect is a change in the frequency of a wave which occurs if one is in a different frame of reference from the emitter of the wave.
text: Stated simply, the Doppler effect is a change in the observed frequency of a wave caused by relative motion between the source of the waves and the observer receiving them.
text: It is a change in the frequency experienced by an observer due to motion of either the observer or the source.
text: The Doppler Effect also called the Doppler shift; it is change in the wavelength or in the frequency of a wave for a viewer who is walking relative to the source of the wave.
text: The "Doppler effect" is the changes in the observed frequencies
text: 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.
text: The Doppler effect is the shift in frequency of a wave that occurs when the wave source, or the detector of the wave, is moving.
text: The Doppler effect is a shift in the apparent or observed frequency and not a shift in the actual frequency at which the source vibrates.
text: Doppler shift is the change in length of a wave (light, sound, etc.) due to the relative motion of source and receiver.
