The apparent shift in the spectrum of a star as it moves toward or away from the earth is explained by the phenomenon known as the?
Doppler effect. This effect causes the wavelengths of light from a star to appear shorter (blueshifted) as it moves towards the Earth and longer (redshifted) as it moves away, providing valuable information about the star's motion in space.
The father the star is away from the earth the more is is?
Redshifted.
What are some objects that are not redshifted?
Objects within the solar system.
What direction will spectral lines move if an object is moving towards you?
They will be blueshifted, that is their wavelengths will be shortened and their frequencies increased.
If light from galaxies is redshifted what can astronomers conclude about galaxies?
That the galaxy is moving away from us.
What 2 types of shifts happen in the Doppler method?
Redshift and Blueshift. Redshift objects are moving away and blueshifted objects are moving towards us.
Why would the star Sirius find that its spectral lines are blue shifted?
The spectral lines of Sirius are blueshifted because the star is moving more or less toward us.
Can the CMBR be redshifted starlight?
The odds are very much against it. The CMB matches expectations following from the Big Bang too well for it to be coincidental.
How red shift connect with universe expanding?
The expansion of the Universe results in the light from faraway galaxies being redshifted. This is called the "cosmological redshift"; it can be compared with the Doppler effect (which also causes a redshift), but the details are somewhat difference.It is an observed fact that most galaxies are redshifted; the explanation that seems most reasonable is that it is caused by the cosmological redshift. This means that space itself is expanding.
A spectral line that appears at a wavelength of 321 nm in the laboratory appears at a wavelength of 328 nm in the spectrum of a distant obect we say that the object's spectrum is?
A spectral line that appears at a wavelength of 321 nm in the laboratory appears at a wavelength of 328 nm in the spectrum of a distant object. We say that the object's spectrum is red shifted.
Where in the universe is red shift observed?
The short answer to this question is "everywhere". Redshift is one aspect of the Doppler effect of light. An observer, looking at an object that emits light, will see the apparent wavelength of that light either compressed to shorter values (if the object is moving toward the observer) or stretched to longer values (if the object is moving away from the observer). Since red light has a longer wavelength than blue light, a stretched wavelength is referred to as a "redshift". It turns out that all of the galaxies in the Universe are moving away from our galaxy, save for a few that are gravitationally bound together into the Local Group of galaxies to which the Milky Way belongs. Therefore, in every direction you look, the sky is full of redshifted galaxies. Within our galaxy, stars have random motions in addition to their general orbits around the galactic center. Some of those motions result in blueshift, some in redshift. So you can find blueshifted stars in every direction you look. But the stars are very local, distance-wise, compared with the redshifted galaxies.
Do plants grow better in sunlight or no sunlight?
sunlight because plants can`t grow without sunlight
