The spectra of most galaxies show redshifts this means that their spectral lines are what?
The spectral lines of galaxies are redshifted, indicating that they are moving away from Earth. This redshift is typically a result of the expansion of the universe, causing galaxies to move further apart.
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.
What element has sky blue spectral lines?
Cesium Indium, as in indigo. (Cesium does burn with a blue colour too but it wasn't named for that trait.)
What is beryllium spectral lines?
Beryllium spectral lines are specific wavelengths of light emitted or absorbed by beryllium atoms when they undergo transitions between energy levels. These spectral lines are unique to beryllium and can be used in spectroscopic analysis to identify the presence of beryllium in a sample.
How the spectrum shift of the dark line supports theory that universe began from a very small point?
1.the observed wavelength of the dark line from the distant galaxy has increased 2.therefore the distant galaxy must be moving away from the Earth suggesting the Universe is 3.expanding outwards from a small initial point
The spectral lines of elements when observed in distant galaxies show a shift towards?
The red end of the spectrum.
Based on the observed red shifts in the spectral lines of distant galaxies?
Astronomers conclude that the universe is expanding, because wavelengths are increasing.
What are the spectral lines of starlight from distant galaxies?
They are the characteristic frequencies of the elements "burning up" in the stars in the galaxy interspersed with absorption lines of other material between these elements and the earth. All these wavelengths will be increased by the red shift which results from the galaxy receding from the earth.
The spectra of most galaxies show redshifts this means that their spectral lines are what?
The spectral lines of galaxies are redshifted, indicating that they are moving away from Earth. This redshift is typically a result of the expansion of the universe, causing galaxies to move further apart.
How do astronomers determine the composition of distant celestial objects?
Spectroscopy is the systematic study of spectra and spectral lines. Spectral lines are used to provide evidence about the chemical composition of distant objects. So the answer to your question is through spectroscopy.. not spectrometry like the previous editor posted.
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.
How do you use spectral lines to determine if a galaxy is moving towards earth or away from earth?
The spectral lines move towards one direction, or towards the other direction, depending on the relative speed.
Who first discovered redshift?
The discovery of redshift in the spectra of light from distant galaxies was made by astronomer Vesto Melvin Slipher in the early 20th century. He noticed that many galaxies appeared to be moving away from us based on the shift of their spectral lines towards the red end of the spectrum. This laid the foundation for the theory of the expanding universe.
The spectra of most galaxies show redshifts this means that their spectral lines?
have wavelengths that are longer than normal:)
When did Hubble discover that the universe was expanding?
Edwin Hubble discovered that the universe was expanding in 1929 when he observed that distant galaxies were moving away from us, as indicated by their redshift in their spectral lines. This discovery led to the formulation of Hubble's law, which describes the relationship between a galaxy's distance and its velocity of recession.
Who discovered the red shift in stars the same effect that causes sound waves to change pitch as an object moves towards or away from an observer?
The red shift in stars was first discovered by astronomer Vesto Melvin Slipher in the early 20th century. He observed that the spectral lines of distant galaxies were shifted towards longer wavelengths, indicating that these galaxies were moving away from us.
What element has sky blue spectral lines?
Cesium Indium, as in indigo. (Cesium does burn with a blue colour too but it wasn't named for that trait.)
