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.
If the spectrum of a star is blue shifted which is the star moving?
If the spectrum of a star is blue-shifted, it indicates that the star is moving towards the observer. This shift occurs because the wavelengths of light from the star are compressed as it approaches, resulting in a shift towards the blue end of the spectrum. This phenomenon is a consequence of the Doppler effect, which applies to all types of waves, including light.
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.
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.
The more spectral lines of a star are shifted to the red end of the spectrum the?
The more spectral lines of a star are shifted to the red end of the spectrum, the more it indicates that the star is moving away from us. This phenomenon is known as redshift, and it is a result of the Doppler effect caused by the expansion of the universe.
What did Hubble conclude when he noted that light emitted from stars is shifting toward the red of the electromagnetic spectrum?
He noted that light emitted from stars is shifted further toward the red of the electromagnetic spectrum . From this he concluded that the universe was expanding.

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 is the Doppler effect observed when two moving objects approach each other?
The Doppler effect observed when two moving objects approach each other is an increase in the frequency of the sound waves or light waves between the objects. This causes the pitch of the sound to appear higher and the color of the light to appear shifted towards the blue end of the spectrum.
If the spectrum of a star is blue shifted which is the star moving?
If the spectrum of a star is blue-shifted, it indicates that the star is moving towards the observer. This shift occurs because the wavelengths of light from the star are compressed as it approaches, resulting in a shift towards the blue end of the spectrum.

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.
How do people know when a star is moving toward or away from the earth?
blue shifted

Who discovered blue shift?
The blue shift phenomenon was discovered by the American astronomer Edwin Hubble in the 1920s. He observed that the light from distant galaxies appeared shifted towards the blue end of the spectrum, indicating that these galaxies were moving away from us. This discovery provided crucial evidence for the expansion of the universe.
The more spectral lines of a star are shifted to the red end of the spectrum the?
The more spectral lines of a star are shifted to the red end of the spectrum, the more it indicates that the star is moving away from us. This phenomenon is known as redshift, and it is a result of the Doppler effect caused by the expansion of the universe.
This is the change in color on the spectrograph as objects move toward or away from objects?
This phenomenon is known as the Doppler effect, where the frequency of light waves emitted by a moving object appears shifted depending on whether the object is moving towards or away from the observer. This shift in frequency causes a change in color on the spectrograph, with objects moving towards us appearing blueshifted (shifted towards the blue end of the spectrum) and objects moving away appearing redshifted (shifted towards the red end of the spectrum).
What is blueshift?
Blueshift is a phenomenon in which the wavelengths of light emitted by an object moving towards an observer are compressed, causing the light to appear shifted towards the blue end of the spectrum. This effect is a result of the Doppler effect and is commonly observed in astronomy when analyzing the motion of astronomical objects.
What is it called when galaxies are moving toward each other?
There isn't a particular name, however, when they are moving towards us, their spectrum is shifted to the blue region. So they are referred to as blue shifted galaxies but that is only relative to ourselves. See related link for more information.
