listen to the pronunciation of doppler etkisi,doppler olayı
Turkish - English
(Nükleer Bilimler) 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
the result of frequencies of waves being observed differently because of the observer's reference frame
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
Change in frequency of sound or lighter due to relative motion of source and receiver
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
The phenomenon in which the frequency of a wave is changed by the motion of the source and/or the observer
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
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
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
  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
A change in the frequency of light or sound waves due to the relative movement between the source and the observer
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
  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
The apparent change in the wavelength of light caused by the motion of the observer
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
The apparent change in wavelength of sound or light caused by the motion of the source, observer or both
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)
change in the apparent frequency of a wave as observer and source move toward or away from each other
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
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
