What does redshifted mean?
The term 'redshifted' describes a change in the wavelength of light or other electromagnetic radiation, resulting in a shift towards the red end of the spectrum. In astronomy, this phenomenon is observed in the light from distant stars or galaxies, indicating that they are moving away from us due to the expansion of space. The term is also used more broadly to describe any change in wavelength of electromagnetic radiation. Understanding redshifted light is crucial in astronomy, as it allows scientists to infer the velocity and distance of celestial objects. The concept of redshifted light has far-reaching implications for our understanding of the universe, from the expansion of space to the properties of light itself.
To cause a shift in wavelength of electromagnetic radiation towards the red end of the spectrum.
"The expansion of space redshifted the light from the distant galaxy."
Describing light or other electromagnetic radiation that has been shifted towards the red end of the spectrum.
"The redshifted light from the star indicated that it was moving away from us."

Etymology of redshifted
The term 'redshifted' is derived from the concept of redshift, which refers to the change in wavelength of electromagnetic radiation. The term 'redshift' was coined in the early 20th century to describe the phenomenon of light shifting towards the red end of the spectrum. The word 'redshifted' is the past tense of the verb 'to redshift', which means to cause a shift in wavelength towards the red end of the spectrum.
How redshifted is actually used
The term 'redshifted' is commonly used in astronomy to describe the phenomenon of light shifting towards the red end of the spectrum due to the expansion of space. It can also be used more broadly to describe any change in wavelength of electromagnetic radiation.
