Doppler effect

The apparent change in frequency or wavelength of a wave that is perceived by an observer moving relative to the source of the waves

doppler effect

An increase (or decrease) in the frequency of sound, light, or other waves as the source and observer move towards (or away from) each other. Named after the Austrian physicist Johann Christian Doppler

Doppler effect

A change in the observed frequency of a wave, as of sound or light, occurring when the source and observer are in motion relative to each other, with the frequency increasing when the source and observer approach each other and decreasing when they move apart. The motion of the source causes a real shift in frequency of the wave, while the motion of the observer produces only an apparent shift in frequency. Also called Doppler shift. Apparent difference between the frequency at which waves including light, sound, and radio waves leave a source and that at which they reach an observer. The effect, first described by the Austrian physicist Christian Doppler (1803-1853), is caused by the relative motion of the observer and the wave source. It can be observed by listening to the blowing horn or siren of an approaching vehicle, whose pitch rises as the vehicle approaches the observer and falls as it recedes. It is used in radar and to calculate the speed of stars by observing the change in frequency of their light

Doppler effect

{i} apparent change in the frequency of sound or light waves due to a change in the distance between the source of the waves and the receiver

doppler effect

the result of frequencies of waves being observed differently because of the observer's reference frame

doppler effect

If an electromagnetic source moves relative to an observer, there is a shift in the observed frequency Also known as Red Shift, if the source is receding from the observer, the observed frequency will appear to decrease

doppler effect

Change in frequency of sound or lighter due to relative motion of source and receiver

doppler effect

an apparent change in the wavelength of energy produced by an object that is caused by the object's motion towards or away from the observer (along the line of sight) In astronomical spectra, the doppler effect is seen in the shifting of spectral lines

doppler effect

The phenomenon in which the frequency of a wave is changed by the motion of the source and/or the observer

doppler effect

The change observed in the frequency with which a wave from a given source reaches an observer when the source and the observer are in relative motion

doppler effect

the phenomena that the frequencies of waves are blue-shifted when the source moves toward the observer and red-shifted when the source moves away from the observer

doppler effect

The apparent change in wavelength of sound or light emitted by an object in relation to an observer's position An object approaching the observer will have a shorter wavelength (blue) while an object moving away will have a longer (red) wavelength The Doppler effect can be used to estimate an object's speed and direction

doppler effect

  The change in the observed frequency (or wavelength) of a wave, caused by a time rate of change in the effective path length between the source and the point of observation

doppler effect

A change in the frequency of light or sound waves due to the relative movement between the source and the observer

doppler effect

An apparent shift in the frequency of a wave For example, when someone is listening to the sound of an ambulance siren, and that person is staying still but the ambulance is driving by, the person will hear a change in pitch of the ambulance siren That change in pitch is caused by the doppler effect The frequency of a sound wave determines the pitch, and the distance of the source of the sound from the sound's observer determines the amount that the frequency seems to have shifted, known as the doppler shift

doppler effect

  The change in the observed frequency (or wavelength) of a wave, caused by a time rate of change in the effective path length between the source and the point of observation

doppler effect

The apparent change in the wavelength of light caused by the motion of the observer

doppler effect

A change in wave frequency (light, sound or other) caused by the compression or elongation of waves as the source moves toward or away from the listener or viewer You've heard the change when an fire engine goes by: The compressed sound rises in pitch, then as the siren moves away, the pitch lowers

doppler effect

The apparent change in wavelength of sound or light caused by the motion of the source, observer or both

doppler effect

The apparent change in wavelength of the light (or radiation) from a source due to its relative motion in the line of sight (i e the direction of the observer)

doppler effect

change in the apparent frequency of a wave as observer and source move toward or away from each other

doppler effect

Slight change in pitch noted when one moves rapidly toward or away from a sound source (or when the latter moves toward or away from the ear) Upon approach, the pitch sounds a little higher; when receding, a little lower

doppler effect

A measurable shift in the wavelength of a traveling wave caused by the relative motion of the source and observer On the straight-aways of the Indianapolis 500, the sound of cars whizzing by an observer changes pitch from high to low As the car approaches at more than 200 m p h , its motion compresses the sound wavelength (high pitch, or short wavelengths); the opposite occurs after the car rushes by (low pitch, or long wavelengths) Light behaves in somewhat the same way Stars with relative motion toward an astronomer appear blue, i e the entire spectrum of star light shifts toward the blue end of the spectrum or is blue-shifted Stars speeding away from the astronomer appear red, i e the entire spectrum is red-shifted This is how astronomers know that the universe is expanding -- most everything is red-shifted

doppler effect

Any motion-induced change in the observed wavelength (or frequency) of a wave

doppler effect

The apparent change in frequency of an electromagnetic wave caused by a change in distance between the transmitter and the receiver during transmission/reception The figure illustrates the Doppler increase that would be realized by comparing the signal received from a target approaching the radar site to the transmitted reference signal An apparent frequency decrease would be noted for targets departing the radar location Differences can be calibrated to provide target range-rate data

doppler effect

An observer receives sound and light from bodies moving away from her with lower frequency and longer wavelength than emitted (see Redshift) and from bodies moving toward her with higher frequency and shorter wavelength The shift in frequency increases as the speed of the body increases

doppler effect

A pitch shift that occurs when a sound source and a listener are moving closer together or further apart Modulating a Delay Time in SFX Machine shrinks or stretches the waveforms, producing a pitch shift that is analogous to the Doppler effect

doppler effect

The change in frequency with which energy reaches a receiver when the receiver and the energy source are in motion relative to each other; also called Doppler shift

doppler effect

the apparent change in wavelength of sound or light caused by the motion of the source, observer or both Waves emitted by a moving object as received by an observer will be blueshifted (compressed) if approaching, redshifted (elongated) if receding It occurs both in sound and light How much the frequency changes depends on how fast the object is moving toward or away from the receiver

doppler effect

Apparent shift in wavelength or frequency as a result of relative line-of-sight motion between the observer and the source of radiation

doppler effect

The apparent change in frequency of sound or light waves, varying with the relative velocity of the source and the observer If the source and observer draw closer together, the frequency is increased Named for Christian Doppler, Austrian mathematician and physicist (1803-1853)
