Redshift. The definition of the redshift z is given in
Chapter 44, Problem 44.34(choose chapter or problem)
Redshift. The definition of the redshift z is given in Example 44.8. (a) Show that Eq. (44.13) can be written as 1 + z = 131 + b4>31 - b421>2, where b = v>c. (b) The observed redshift for a certain galaxy is z = 0.700. Find the speed of the galaxy relative to the earth; assume the redshift is described by Eq. (44.14). (c) Use the Hubble law to find the distance of this galaxy from the earth
