The Cosmic Background Radiation Outer space is filled with a sea of photons, created in the early moments of the universe. The frequency distribution of this "cosmic background radiation" matches that of a blackbody at a temperature near 2.7 K.
Part A What is the peak frequency of this radiation?
Part B What is the wavelength that corresponds to the peak frequency?
