Lesson: Hubble’s Law Physics

Students will be able to

• recall that light from objects moving away from us is redshifted,
• recall that light from objects moving toward us is blueshifted,
• recall that the further away a galaxy is, the greater its redshift is and the faster it is moving away from us,
• use (Hubble’s law) in all permutations,
• interpret graphs of radial velocity against distance or redshift against distance.
