What is The apparent change in position of an object with respect with respect to a distant background is called?
Parallax id the apparent shift in position of an object with respect to the background due to a shift in view point.
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.
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 is red-shift and what does the size of the redshift tell us about the distant galaxies?
Red shift is the apparent elongation of the wavelength of light reaching us from distant sources of light due to the expansion of space in between. The amount of red shift can be used to work out the recessional velocity of a galaxy and it's distance from us.
Can a red shift and a blue shift exist on the same object at the same time?
No.
How does the focal length of the lens change when you sift looking from a distant object to nearby object?
The focal length of the lens can be changed by the ciliary muscles in the eye due to which we can shift looking from a distant object to nearby object .
What is The apparent change in position of an object with respect with respect to a distant background is called?
Parallax id the apparent shift in position of an object with respect to the background due to a shift in view point.
What is it called when the apperent shift in the position of an object when viewed from two locations?
Parallax is the apparent difference in the position of a nearer object, compared to more distant background objects, when viewed from two different positions.

How can two different opbjects with different speeds give off the same red shift?
No one ever said that they do. In fact, the only way we know a distant object's [radial] speed is through its red shift. So if two objects have the same red shift, then as far as anybody knows, they have the same speed.

No.
Can there be purple shift aswell as blue shift and red shift?
Redshift and blueshift refer to a change in frequency of light we receive from distant objects (stars, galaxies, etc.) The light can turn different colors, and purple is one of them. However, no matter what the color the light changes to, the technical term is always "redshift" if the frequency of the light decreases (normally indicating that the object is moving away from us), and "blueshift" if it increases (normally indicating that the object is moving towards us). Blue shift and purple shift would mean the same thing because the spectrum is one-dimensional. It's like if you are in Boston, a shift towards Chicago is the same as a shift towards San Francisco. Obviously, a purple shift is a super blue shift.
What does red shift show?
The red shift shows the velocity with which an object is moving away from the earth. The red shift of an object is correlated to its distance from the earth and so it is also a measure of the distance.
What did hubble discover as a result of studying red shift of distant galaxies?
that the universe was in 1904 expanding. this was due to the lack of blue shift, therefor it can be deduced that the red shift in orrcuring within the galaxy.
