Why the red shift in light from distant galaxies indicate that the universe is expanding?
Red shift is observed in the spectrum of light from an object when it is moving away from the observer. Most astronomical objects display a red shift in their light. Also, the red shift is greater for objects which are further away. For this to happen - in all directions, the universe must be expanding.
What shift i the spectrum would there be if a star is moving at right angles to the direction of sight?
No shift at all.
What type of shift in the spectrum would you expect from a star that was moving in the same direction as earth at the same speed of earth?
You would expect no shift in its spectrum. Any shift one way or the other is the result ofmotion either toward or away from Earth. Motion parallel to ours or across our line of sighthas no effect on the observed spectrum of the object.
How are Doppler blue and red shift different?
A blue shift is observed in the spectrum from an object approaching the observer whereas a red shift is observed for a receding object.
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 part of the spectrum does the spectrum of distant light shift to?
It is called red-shift. It shifts to the longer-wavelength, shorter-frequency direction. For example, visible light shifts towards the infra-red area of the spectrum.

What are differences in colors of moving objects in space that are approaching and moving objects that are moving away?
Objects moving toward you will have a blue shift in their spectrum and objects moving away from you will have a red shift in their spectrum. This is known as a doppler shift.
What is the for the change in a stars spectrum when it moves away from earth?
Doppler shift

What Evidence shows galaxies are moving in relation to the earth position?
Look at the spectrum of lite from a galaxy if there is a red shift the galaxy is moving away from us or a blue shift the galaxy is coming toward us most have a red shift due to expansion of the universe we are all flying away from another

Doppler effect states that the motion of any object can?
Shift the wavelength of the spectrum.
In the universe what is the red shift?
The alterations to the electromagnetic spectrum caused by the expansion of the universe.
What is the name for the change in a stars spectrum when it moves away from the earth?
It is called The Doppler Shift
