- Red Shift
- Doppler effect
- Wave changes freq. as wave source + observer move relative to each other
- Wave source moving towards observer - wavelength decreases + freq. increases - BLUE SHIFTED
- Opposite if wave moving away from observer
- Faster Galaxy moves = larger shift
- More distant Galaxy's are travelling faster
- Universe expanding
- More distant Galaxy's are travelling faster
- Wave source moving towards observer - wavelength decreases + freq. increases - BLUE SHIFTED
- Wave changes freq. as wave source + observer move relative to each other
- Doppler effect
