- p1.6 red shift
- The doppler effect
- The change of frequency
- if the source moves towards the observer we get a decreased wavelength and increased frequency
- This makes the light bluer - known as blue shift
- If the source moves away from the observer we get increased wavelength and decreased frequency
- this makes the light redder - known as red shift
- The colour of light
- Red light has the longest wavelength
- violet light has the shortest wave length
- Richard Of York Gave Battle In Vain ..... Red, Orange, Yellow , Green, Blue, Indigo , Violet
- dark lines of a distant galaxy are shifted towards red part - called red shift, makes waves longer
- Distant galaxies moving away from us
- The faster a galaxies is moving, the bigger the red shift
- Hubbles law
- Level of red shift in a light galaxy increases with its distance from the earth
- The universe is expanding
- v = H x d V is velocity, H is hubbles constant, d is distance
- Level of red shift in a light galaxy increases with its distance from the earth
- The big bang
- universe started 13 million years ago with a massive outpouring of energy
- the theory states : the universe is expanding after exploding from a very small initial point and space time and all matter was created in the big bang
- issues such as religious and lack of evidence
- The doppler effect
