  1. Redshift questions

  2. Red shift

  3. Big bang

  4. Less/ no light pollution Less atmospheric distortion/ interference Less/ no cloud cover Image is clearer

  5. Light is red shifted The further away the galaxy is, the bigger the effect The universe is expanding

  6. Observed – original = Z x orginal Observed – 600 = 0.15 x 600 = 90 600 + 90 = 690

  7. Distance from the Earth Speed the stars/ galaxies are moving away from the earth

  8. The microwave radiation comes from radiation present just after the big bang The big bang is currently the only way of explaining CMBR The wavelength is decreased and the frequency increased

  9. Red shift

  10. It is furthest away; it has the largest red shift; it is moving away the fastest. C

  11. The observed wavelength of the dark line from the distant galaxy is increased Therefore the distant galaxy must be moving outwards from a small initial point This suggests the universe is expanding

  12. The existence of CMBR
