What does a red shift in the spectrum of light from an object indicate about the object?
Usually, that the object is moving away from us. It may also mean that the light comes from a "gravitational well", that is, that the light has to escape from gravity before it reaches us - this will make the light lose some energy, and shift towards the red part of the spectrum.
What does a red shift in the spectrum of light from an object indicate?
The visible spectrum contains two ends, infrared and ultraviolet. A shift of light towards the infrared end typically indicates the object is receding from the observer. Another explanation is that the object may be entering a deep gravity well, which would also stretch and distort light reflected or emitted from the object.
What does redshifts indicate to astronomers?
The object is moving away from the observer.
Would a light source moving away from Earth appear blue shifted or red shifted?
A red shift indicates an object that is moving away from the observer, and a blue shift indicates an object that is moving toward the observer. Both of these are called Doppler shifts.
When an object reflects the entire spectrum of light how does it look?
White

What happen if a light move closer to the object?
The redshift that scientists speak of in stars, indicating that they are moving away, is complemented by a shift toward the blue in the spectrum by light moving toward a viewer.
What does the blue shift in the spectrum of light from an object indicate the object is moving?
A blue shift in the spectrum of light from an object would indicate that the object is moving towards the observer. The blue shift indicates that the object is under centripetal force. The object may not be moving toward the center if it is balanced by centrifugal force (repulsion) from the center.
What does the blue shift mean in regard to stars and galaxies?
Light is a spectrum. On one end it is red and the other blue. We see light in this spectrum as waves and if it is blue, the object is coming toward us. If the waves are red than it is moving away. The frequency of these waves tell us how fast and object is moving toward or away from us.

How can spectrum tell us if an object is reflecting blue light from a star?
how can you tell if an object is reflecting blue light from a star
When the wavelength of a spectral line emitted from an object increases which end of the visible light spectrum does not move toward and what is the objects 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.
What is a use of examining light spectra?
One use of light spectra has an application in astronomy. When looking at distant objects like galaxies, you can tell if they are moving away from you or closer to you. If the spectral light appears blue (blue-shift) it means that the object is moving toward you, if the spectral light is red (red-shift) it means that the object is moving away from you. Another astronomy application is to look at the light from a star through a spectrum and by doing so you can figure out the chemical composition of the star just by the color of its spectrum.
What is the difference between red light and a red object?
Red object is one that absorb other range of spectrum but Red light.
