Iwill award you with 60 ! when the wavelength 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?

Increasing wavelength is an indication of a Doppler shift caused by an object moving away from the viewer. Longer wavelengths (of the visible spectrum) are redder, shorter wavelengths are bluer. Objects moving away from you have a red shift, objects moving toward you have a blue shift.
