What the syllabus asks
- understand that the lines in the emission spectra from distant objects show an increase in wavelength from their known values
- use ∆λ / λ . ∆f/f . v / c for the redshift of electromagnetic radiation from a source moving relative to an observer
- explain why redshift leads to the idea that the Universe is expanding
- recall and use Hubble’s law v . H0d and explain how this leads to the Big Bang theory (candidates will only be required to use SI units)
