Question

Redshift means stars and galaxies are emitting a color that is shifting toward the red end of the color spectrum. This indicates the light's wavelengths are and less frequent, and the star or galaxy is .

Answer 1

Hey mate!!

Here's the answer

Answer;

-The light's wavelengths are larger and less frequent, and the star or galaxy is moving away from us.

Explanation;

-Redshift and blueshift describe how light shifts toward shorter or longer wavelengths as objects in space (such as stars or galaxies) move closer or farther away from us.

For example; doppler redshift occurs if the source of light is moving away from an observer, causing the wavelength of the light to be shifted towards the red due to an apparent increase in wavelength (waves spread). A doppler blueshift occurs if the source of light is moving towards an observer, causing the wavelength of the light to be shifted towards the blue due to an apparent shortening of wavelength (waves squeeze together).

-Visible light is a spectrum of colors, which is clear to anyone who has looked at a rainbow. When an object moves away from us, the light is shifted to the red end of the spectrum, as its wavelengths get longer. If an object moves closer, the light moves to the blue end of the spectrum, as its wavelengths get shorter.

Hope this helps you

Answer 2

Moving away from the observer.

Redshift means stars and galaxies are emitting a color that is shifting toward the red end of the color spectrum. This indicates the light's wavelengths are and less frequent, and the star or galaxy is moving away from the observer.

• Redshift is the term used to describe how stars and galaxies are emitting light that is moving from the blue end of the spectrum to the red. This suggests that the star or galaxy is moving away from the viewer and that the light's wavelengths are LONGER and less frequent.
• A star's redshift indicates its distance from Earth since an increasing wavelength is indicated by the colour red in the spectrum.
• A redshift shows how fast or slowly, in relation to us, an object in space is travelling. It enables astronomers to calculate the separation between the oldest and most remote objects in the universe.
• Depending on whether an object is travelling toward us or away from us, the frequency of a light wave will vary. This phenomenon is referred to as redshift and blueshift. Blueshift is the name for an object's light while it is moving toward us, and redshift is the name for an object's light when it is moving away from us.
