The Cosmic Microwave Background is radiation that was initially emitted about 300,000 years after the Big Bang when the Universe was at a average temperature of approximately 3,500 K. Over time, this radiation has red-shifted so that the average temperature of the Universe today is 2.73 K. Using the value from today, 2.73 K, estimate the wavelength of peak radiation coming from the Cosmic Microwave Background as we see it now. a. 0.001 m
