Question

If c=λf, write out the equation needed to solve for the speed u of the galaxy. Your answer should be in the form u = ...

Answer 1

Answer #1

Since C=lambda*f

Also ,According to Hubble's Law,

We have the relation as

U= H_od

Where U= velocity of a galaxy, in km/s

H_o = Hubble Constant, in km/s/Mpc approximately 500 km/s/Mpc or about 160 km/sec per million-light-years

d = distance of a galaxy, in Mpc (mega-parsecs)

We can impress the value of lambda in accordance with the distance of galaxy in the above formula and hence we can get our desired result.
