Sept 20-27: Doppler & Spectral Analysis

This week we're going to talk about the Doppler Effect... you know, that weird noise you hear when an ambulance or train passes. The Doppler Effect not only applies to sound however, it applies to all things that travel in waves - including light. Astronomers have used the Doppler Effect on light to determine that the universe is expanding... pretty cool huh? So this week we're going to talk about how stars and galaxies are analyzed and how the colors of the spectrum apply to the Doppler Effect and the Big Bang Theory. It's very cool stuff, and your student would definitely benefit from your asking him/her to explain it to you! Teaching is the best way to learn... believe me.
