Question

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 2.7K. What is the peak frequency of this radiation in Hz? What is the wavelength that corresponds to the peak frequency in mm?

          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 2.7K. What is the peak frequency of this radiation in Hz? What is the wavelength that corresponds to the peak frequency in mm?

Step 1

According to Wien's displacement law, the peak wavelength (λ) of blackbody radiation is given by the equation λ_peak = b / T, where b is Wien's displacement constant (approximately 2.897 x 10^-3 m*K) and T is the temperature in Kelvin. Show more…
