Unit 2 reintroduced me to the Doppler Effect, which I had forgotten, and continued with RedShift, which I don't recall having ever learnt. However, as I studied physics back in the dark ages, including Einstein's theory of relativity, I assume I must have.
Finishing the unit, I bounced around the internet reading more on this. I liked the simplicity of the illustration below, and found space.com a good site for info, but nasa.gov was a bit complex.
