Question

if galaxy A is more red shifted than galaxy B. thus we can conclude that
a)velocityof galaxy A is more than galaxy B
b)velocity of galaxy B is more than galaxy A
c) both have equal velocity
d)both the galaxies are at rest

which of tthe 4 options are correct?

Answer 1

redshifts depends upon relative speed or it is a simple example of a doppler effect
thus more redshift farther the object will be farther object more be the velocity
so 
a is the correct answer
