When the wavelength increases, what is the object’s motion relative to Earth?

When the wave length of spectral lines emitted from an object increases, which end of the visible light spectrum does it move toward, and what is the object's motion relative to Earth? The light spectrum it moves toward when an object increases is the red shift, and it is moving away from earth.

Explanation:

answer they showed that organic molecules such as amino acids could be produced from inoragnic molecules;
