each star displays its own absorption spectrum. when a star is moving away from earth, the absorption bands are shifted toward the red end of the spectrum, known as redshift. the faster the star is moving away from earth, the greater redshift will be. the spectrum a particular star would display without any redshift is shown. which spectrum would indicate the star was moving away from earth at the fastest speed?

Answer

Explanation:

Step1: Understand redshift concept

The faster a star moves away from Earth, the greater the redshift (shift towards the red - end of the spectrum).

Step2: Analyze options

We need to find the spectrum with the most significant shift towards the red - end. Looking at the options, we compare the positions of the absorption bands relative to the original spectrum. The spectrum with absorption bands shifted the most towards the red (right - hand side) indicates the fastest - moving star.

Answer:

The option with the absorption bands shifted the most towards the red end of the spectrum (the right - hand side in the given spectra). Without seeing the exact shifts in each option clearly from the provided image, if we assume the options are ordered in terms of shift, the one with the maximum shift to the right would be the answer. If we had to guess based on the principle, it would be the option where the absorption bands are furthest to the right compared to the others.
