As light travels, its wavelength can lengthen or shorten causing it to appear more red the further it travels or more blue if it has traveled a shorter distance. This effect, combined with various chemical spectral identifiers, can be used to determine the distance the light has traveled, giving a rough estimate to the location of its source.
changes in wavelength is called redshift(when wavelength is increased) and blueshift(when decreased). redshifts and blueshifts are attributable to the Doppler effect

∙ 11y agoAs light travels even through free space (vacuum) its energy would be absorbed by the non material medium. Because free space has magnetic and electric properties.
