According to Hubble's law, the redshift (Z) of a receding galaxy and its distance r from earth are related as

A

`Z prop r`

B

`Z prop 1//r`

C

`Z prop 1//r^(2)`

D

`Z prop r^(3//2)`

Text Solution

Verified by Experts

The correct Answer is:
A
Hubble's law is a statement of a direct correclation between the distance (r ) to a galaxy and its recessional velocity as determined by the red shift (Z).
It is stated as `Z=H_(0)r`,
where Z= recessional velocity
`H_(0)=` Hubble constant and r= distance.
