###### Question details

PA. Calculate the peak wavelength of the background radiation at the time light left the most distant galaxies we can currently see. Assume those galaxies have a cosmological redshift of z = 10 and that the current peak wavelength is 1.1 mm (as found from Wien's law). Express your answer using two significant figures. PB. What is the temperature corresponding to that peak wavelength? Express your answer using two significant figures.
