Hubble’s law and the Big Bang theory past paper questions

A2 Physics 9702 · Astronomy and cosmology. 1 understand that the lines in the emission and absorption spectra from distant objects show an increase in wavelength from their known values 2 use ∆λ / λ . ∆f / f . v / c for the redshift of electromagnetic radiation from a source moving relative to an observer 3 explain why redshift leads to the idea that the Universe is expanding 4 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)

In Cambridge A Level A2 Physics 9702, Hubble’s law and the Big Bang theory came up in 17 of the 42 papers on Paperstreak, for about 6 marks a paper when it does. It last came up in October/November 2025.
