Question

For "moving toward," a blue ray of light moved from the star to Earth. Then a spectrum appeared in the bottom half of the screen. Which statement about the spectrum on the bottom relative to the spectrum of the stationary star is correct?

Answer 1

It travels faster

Step-by-step explanation:

The spectrum are likely to be of different wavelengths. The different wavelengths result in light of a different intensity. This results in a light difference in the spectrum. The blue ray generally presents light of shorter wavelengths. It is associated with close to hottest objects. Thus, there will bee a difference in the two spectra.
