From earth, a hydrogen source releases an emission line that has a wavelength of 410nm. observations have been made for the same

line in the spectrum of light from a distant star. the star has a wavelength of 485nm (shifted toward the red end of the spectrum). provide an explanation for the differences in wavelength that were observed.

The explanation for the differences in wavelength observed from earth and a distant star with a shift towards the red end of the spectrum is the Redshift- Doppler effect.

<h3>What is the Doppler effect?</h3>

The Doppler effect is the difference that occur between the frequency of a wave in relation to observer from the wave source.

The wavelength changes with change in the frequency.

<h3>How does the Doppler effect explain the redshift?</h3>

As an object moves away from Earth, the waves moves to the red end of the electromagnetic spectrum and becomes elongated. This results to the increase in wavelength.

Therefore, the explanation for the differences in wavelength observed from earth and a distant star with a shift towards the red end of the spectrum is the redshift-Doppler effect.
