- Problem 2 When Observing A Galaxy The Calcium Absorption Line Which Has A Rest Wavelength Of 3933 A Is Observed Redshi 1 (37.32 KiB) Viewed 45 times
Problem 2. When observing a galaxy the calcium absorption line, which has a rest wavelength of 3933 A is observed redshifted to 3936.5397 A. a)Using the Doppler shift formula calculate the cosmological recession velocity Vr, (c = 300 000km/s). b)Evaluate the Hubble constant H (in units of km/s/Mpc), assuming that the Hubble law Vr = Hd holds for this galaxy. The distance to the galaxy is measured to be 4 Mpc.
