Light spectra shifted towards red

İlgili Terimler

redshift
A change in the wavelength of light, in which the wavelength is longer than when it was emitted at the source
redshift
a shift toward longer wavelengths of the radiation caused by the emitting object moving away from the observer When this occurs we see the light from the object become more red See also Doppler effect
redshift
Displacement of the spectrum of an astronomical object toward longer wavelengths (visible light shifts toward the red end of the spectrum). In 1929 Edwin Hubble reported that distant galaxies had redshifts proportionate to their distances (see Hubble's constant). Since redshifts can be caused by motion of an object away from the observer (the Doppler effect), Hubble concluded that all galaxies are receding from each other. This became the cornerstone of theories of an expanding universe
redshift
{i} shift toward the longer wavelengths in the spectral lines emitted by a heavenly body (caused when an object is moving away from an observation point)
red shift
(astronomy) a shift in the spectra of distant galaxies toward longer wavelengths; generally interpreted as the Doppler effect resulting from the velocity at which they recede as the universe expands
redshift
Redshift is the displacement of electromagnetic radiation such as light to longer wavelengths because the source of the radiation is moving away from the observer Redshift is a kind of doppler shift All material in the Universe, except for the closest few galaxies in our own Local Group, are moving away from us and therefore their light shows redshift From the measured redshift we can determine the distance of the source, through Hubble's Law
redshift
–An increase in the wavelength of radiation received from an astronomical body as a consequence of the Doppler effect; a shift toward the long (red) end of the electromagnetic spectrum

redshift
displacement of spectral lines toward the longer wavelengths arising from the Doppler shift
redshift
A shift to longer wavelengths of light, typically a Doppler shift caused by the motion of the source away from the observer
redshift
When the light an object emits is displaced toward the red end of the spectrum it is said to be redshifted In general, photons of light that are emitted at a source at one energy and detected by an observer at a lower energy are redshifted Often, the redshift of an object can be measured by examining atomic absorption or emission lines in its spectrum Redshifts can be caused by the motion of a source away from an observer For distant objects, redshifts can be caused by the expansion of the Universe
redshift
The amount that wavelengths of light and radiation from distant galaxies and quasars are increased because of the expansion of the Universe
redshift
A shift in the wavelength of light (or other electromagnetic radiation) toward the red end of the spectrum
redshift
A Doppler shift of spectral features or light toward longer wavelengths, indicating recession of the source or observer
redshift
The shifting of the spectrum of a star or galaxy due to radial velocity (meaning velocity toward or away from the observer, in this case, us) The shift is caused by the Doppler effect, and through Doppler's equation, we can convert shift to radial velocity While this is commonly called redshift, the spectrum could also be shifted the other way, blueshifted, if the star or galaxy were heading toward us rather than away The redshift is useful in exploring other galaxies because it can give us an idea of the distance to the galaxy via Hubble's Law
redshift
An apparent shift toward longer wavelengths of spectral lines in the radiation emitted by an object caused by motion of the emitting object away from the observer
redshift
Displacement of the spectral lines in light coming from the stars of distant galaxies, thought to be produced by the velocity of the galaxies outward in the expanding universe
redshift
The shift of spectral lines to longer wavelengths either due to the motion of the source away from the observer or very strong gravity
redshift
target redshift from proposal
redshift
The shift of all the spectral lines toward longer wavelengths due to the object's recession as seen from the Earth, this recession, at great distances, is due to the overall expansion of the Universe
redshift
the shift of spectral lines from an object to longer wavelengths because the object is moving away from the observer The greater the speed of the object, the greater the redshift will be
redshift
A shift in the lines of an object's spectrum toward the red end Redshift indicates that an object is moving away from the observer The larger the redshift, the faster the object is moving
