dopler kayması

التركية - الإنجليزية

تعريف dopler kayması في التركية الإنجليزية القاموس.

doppler shift

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

1 = Doppler effect

The apparent change in the frequency of a signal caused by the relative motion of the transmitter and receiver

The change in length of a wave (light, sound, etc ) due to the relative motion of source and receiver Things moving toward you have their wavelengths shortened Things moving away have their emitted wavelengths lengthened

a phenomenon that causes waves to have a longer wavelength if the source and observer are moving apart and conversely becomes shorter if they are moving together Very useful effect for flow and speed measurement

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

  The degree of observed change in frequency (or wavelength) of a wave due to the doppler effect

Change in wavelength due to relative motion source and detector The change in the wavelength of sound emitted by a moving source (Ex Moving Fire Truck Siren, Moving Car Horn, Moving Train )

The apparent change in frequency of a received signal due to the rate of change of the range between the transmitter and receiver See reconstructed carrier phase

The apparent change in the frequency of a signal caused by the relative motion of the transmitter and/or the receiver

A change in the perceived frequency of a radiated signal caused by motion of the source relative to the observer

A change in the wavelength of radiation received from a source because of its motion along the line of sight A Doppler shift in the spectrum of an astronomical object is commonly known as a redshift when the shift is towards longer wavelengths (the object is moving away) and as a blueshift when the shift is towards shorter wavelengths (the object is approaching)

A shift occurring in the electromagnetic spectrum, where an apparent change in signal frequency occurs as the transmitter and receiver move toward or away from one another
