What is indicated by a shift of galaxy spectral line toward the red part of its spectrum?
In simplest terms, the shift of galactic spectral lines towards the red end of the spectrum would indicate simply that the galaxy in question is receding from the observer. This is an example of the Doppler effect, where the frequency is lowered (wavelengths become longer, and in this case energy of the photons is decreased) by the relative motion of the observer. The redshifting of galaxies in all directions became the primary evidence of an expanding universe (cosmological redshift). Because the expansion of the universe is fairly uniform in all directions, those galaxies that are most distant are receding the fastest and thus evidence the greatest amount of redshift.
By contrast, if a characteristic spectral line of a galaxy or other object shifted towards the blue end of the spectrum (shorter wavelengths), it would be traveling towards the observer.
What else can I help you with?
When the absorption lines of a galaxy shifts toward the blue end of the spectrum it means that that the galaxy?
It means the heading towards us, red means it is moving away from us.
What diagram best represents the pattern of spectral lines from the same element when it was observed by Edwin Hubble in the light of one of the distant galaxies?
The best diagram to represent the pattern of spectral lines from the same element observed by Edwin Hubble in the light of distant galaxies is the redshift spectrum. This spectrum shows the spectral lines of elements shifted toward longer wavelengths (redshifted) due to the Doppler effect, indicating that the galaxies are moving away from us. The pattern of these lines remains consistent with the element's known absorption or emission spectrum, but the entire set of lines shifts uniformly to the red, reflecting the expansion of the universe.
Why the positions of the spectral lines of barnard's star are all shifted toward the blue end of the spectrum?
The spectral lines of Barnard's Star are shifted toward the blue end of the spectrum due to the Doppler effect, indicating that the star is moving towards us. This blue shift occurs because the wavelengths of the light emitted by the star are compressed as it approaches, resulting in higher frequency and shorter wavelength light. This motion can be attributed to the star's proper motion relative to Earth. Such shifts are crucial for astronomers to understand stellar dynamics and distances.
When the wavelength of a spectral line emitted from an object increases which end of the visible light spectrum does not move toward and what is the objects motion relative to earth?
Increasing wavelength is an indication of a Doppler shift caused by an object moving away from the viewer. Longer wavelengths (of the visible spectrum) are redder, shorter wavelengths are bluer. Objects moving away from you have a red shift, objects moving toward you have a blue shift.
How do astronomers determine the speed at which a galaxy is moving?
By examining its spectrum, and identifying absorption lines in it. Lines are shifted toward shorter wavelength if the object is moving towards us. They're shifted toward longer wavelength if the object is moving away from us.
Does the velocity of a star toward or away from earth determine measuring the shift of its spectral lines?
Yes. If the star is moving away from the Earth, its spectral lines will shift towards the red end of the spectrum. If it is moving towards the Earth, its spectral lines will shift towards the violet end of the spectrum. This is due to Doppler effect.
What would evidence of a galaxy moving toward Earth?
A blueshift in the galaxy's spectrum - that is, the frequency of the light, as observed by us, is greater than when it was emitted.
When the wavelength of a spectral line emitted from an object decreases which end of the visible light spectrum does it move toward and what is the object and motion relative to Earth?
When the wavelength of a spectral line emitted from an object decreases, it moves toward the blue end of the visible light spectrum. This phenomenon indicates that the object is moving toward Earth, a scenario known as blue shift. Common examples include distant galaxies or stars that are moving closer to us.
When the wavelength of spectral emitted from an objectincreases which end of the visiblelight spectrum does ti move toward and what is the objects motion relative to earth?
When the wavelength of spectral light emitted from an object increases, it moves towards the red end of the visible light spectrum, also known as the redshift. This indicates that the object is moving away from Earth.
When the absorption lines of a galaxy shifts toward the blue end of the spectrum it means that that the galaxy?
It means the heading towards us, red means it is moving away from us.
When the absorption line of a galaxy shift toward the blue end of the spectrum it means that the galaxy is?
It means the heading towards us, red means it is moving away from us.
When the wavelength of the spectral line emitted from an object decreases which end of the visible light spectrum does it move toward and what is the object's motion relative to Earth?
If the wavelength decreases, the spectral line moves towards the blue end of the visible light spectrum. This phenomenon is known as blue shift, indicating that the object is moving towards Earth.
When the wavelengths of spectral lines emitted from an object decreases with end of the visible light spectrum as it moves toward?
When the wavelengths of spectral lines emitted from an object decrease toward the end of the visible light spectrum, it indicates that the object is moving toward the observer, a phenomenon known as the blue shift. This occurs due to the Doppler effect, where the frequency of light waves increases as the source approaches the observer. Consequently, the emitted light shifts toward shorter wavelengths, which can provide information about the object's velocity and motion in space.
When the wavelength of spectral lines emitted from an object decreases which end of the visible light spectrum does it move toward and what is the objects motion relative to earth?
When the wavelength of spectral lines emitted from an object decreases, it moves towards the violet end of the visible light spectrum. This is known as a blueshift, indicating that the object emitting the light is moving towards Earth.
What is the color of spectrograph as objects move forward or away from the objects?
As objects move away from an observer, their light is redshifted, meaning the spectral lines shift toward the red end of the spectrum, indicating longer wavelengths. Conversely, when objects move closer, their light is blueshifted, with spectral lines shifting toward the blue end of the spectrum, indicating shorter wavelengths. This phenomenon is primarily due to the Doppler effect, which affects how we perceive the wavelength of light from moving objects.
