It means the heading towards us, red means it is moving away from us.

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.
In the field of spectroscopy absorption a peak means the wavelength of radiation where a sample absorbs. Different molecules absorb radiation of different wavelengths. An absorption spectrum will show a number of absorption bands, each one corresponding to structural groups within the molecule. Each band is represented by peak if you plot absorbance vs wavelength. By knowing which structural groups correspond to which peaks, you can often identify a compound by it's spectrum. For many molecules, the spectrum has been characterized, and you can use the spectrum to determine the purity, concentration, or other properties of the molecule by looking at the position and intensity of the peaks in the absorption spectrum.
Most stars have absorption spectra. In other words, stars possess thin outer layers that allow light to pass through. These layers produce what are called absorption lines. This means the light from the sun and stars are absorption spectra.
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.
because they will have the same elements in the atmosphere...
If the spectrum of a star shows the same absorption lines as the sun than you know that the star has the same composition as the sun. This means that the star is made of the same elements as the sun.
bacause the spectrum means spectrum so the spectrum is known as spectrum is called as spectrum
Negative absorption in a UV-Vis absorption spectrum is typically a result of solvent effects or instrument noise. It does not have a physical meaning and should be disregarded when analyzing the data. It is important to ensure proper calibration and sample preparation to minimize such artifacts.
the galaxy means that if you get to galaxy you will be dead................HEHEHEHEHEHeheheh
As the name suggests,hydra refers to water and hence hydration means absorption of water and fluid absorption means absorption of any liquid or gas. lol
nice question! actually when a wave approaches an observer the wave length of the wave decrease and as it move far from us its wavelength increase. it is quiet difficult to understand so use your imagination. as the wavelenght increase the spectrum will be shifted toward red spectrum and thus called red shift. when Edward Hubble studies spectrum of different star he noticed that because of some color spectrum were missing, other spectrum got shifted to ward red. it it moved toward red then that mean that wavelength was increasing and if wavelength increases then that means light moves away from us and thus he concluded that each and every star and galaxy was moving away from each other. so blue shift doesn't support big bang. inversely, blue shift support big crunch.
