What happen to the spectrum of a star moving toward the earth away from the earth?
If a star is moving towards Earth. The light is seen as 'blue shifted'. As we look at our sun, on the colour spectrum, black lines appear. When looking at distant stars, we can tell if they are moving away from us (Red shift) or getting closer to us (Blue shift). This is because the black lines shift to the red or blue end of the spectrum depending on which direction the star is travelling.
What else can I help you with?
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.
If a galaxy is moving towards the earth what direction does its spectrum move?
If a galaxy is moving towards the Earth, its spectrum will be blueshifted. This means that the wavelengths of its emitted light are compressed, resulting in a shift towards the blue end of the spectrum.
Observation of the shift of a stars spectrum toward the red or blue enables us to determine the stars?
Observation of the shift of a star's spectrum toward red indicates it is moving away from us (redshift), while blue indicates it's moving closer (blueshift). By studying this shift in the star's spectrum, we can determine its velocity and distance from Earth, providing valuable information about its motion and location in space.
Why is the Andromeda galaxy moving toward earth?
Sorry, Andromeda and earth are moving away from each other, not towards each other.
When the spectrum of light from a star is Redshifted the star must be what?
When the spectrum of light from a star is redshifted, it indicates that the star is moving away from the observer. This is due to the Doppler effect, where the wavelengths of light stretch, causing them to shift toward the red end of the spectrum. Redshift can also suggest the star is part of an expanding universe, as seen in distant galaxies. Overall, redshift is a key indicator of the star's velocity relative to Earth.
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.
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 does a shift toward the blue end of the spectrum mean?
A shift toward the blue end of the spectrum means that the light being observed has a higher frequency and shorter wavelength compared to light at the red end of the spectrum. This shift is known as "blue shift" and is commonly seen in scenarios where the light source is moving closer to the observer, such as with objects moving towards Earth in the universe.
What does the spectrum of a star determine?
The spectrum of a star provides information about its temperature, composition, and motion. By analyzing the spectrum, astronomers can determine the star's chemical makeup, age, and even whether it is moving toward or away from Earth.
If a star is moving toward Earth it is?
If a star is moving toward Earth, it will experience a redshift in its light spectrum due to the Doppler effect. This means that the wavelengths of light will be stretched and appear more red. This effect allows astronomers to measure the speed and direction of a star's movement.
What type of shift in the spectrum would you expect from a star that was moving in the same direction as earth at the same speed of earth?
You would expect no shift in its spectrum. Any shift one way or the other is the result ofmotion either toward or away from Earth. Motion parallel to ours or across our line of sighthas no effect on the observed spectrum of the object.
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.
If a galaxy is moving towards the earth what direction does its spectrum move?
If a galaxy is moving towards the Earth, its spectrum will be blueshifted. This means that the wavelengths of its emitted light are compressed, resulting in a shift towards the blue end of the spectrum.
Observation of the shift of a stars spectrum toward the red or blue enables us to determine the stars?
Observation of the shift of a star's spectrum toward red indicates it is moving away from us (redshift), while blue indicates it's moving closer (blueshift). By studying this shift in the star's spectrum, we can determine its velocity and distance from Earth, providing valuable information about its motion and location in space.
If a star is moving toward earth is it?
blue shifted
Is a star is moving toward earth it is?
blue shifted
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.
