Physics

Suppose that you have obtained spectra of several galaxies andhave measured the observed wavelength of the H-alpha line (restwavelength = 656.3nm) to be:

Galaxy 1: 659 nm. Galaxy 2: 666.5 nm. Galaxy 3: 676.6 nm.

10. [4pt] Calculate the redshift, z, for each of thesegalaxies.

11. [4pt] Calculate the radial velocity of each of thesegalaxies.

12. [4pt] Assuming a Hubble Constant of 69.6 km/s/Mpc, cal-culate the distance to each of these galaxies (answer in Mpc).
