Question:
Use Wien's law (see Problem 44) to answer the following questions:
(a) The cosmic background radiation peaks in intensity at a wavelength of 1.1 mm. To what temperature does this correspond?
(b) Ab out 379 000 y after the big bang, the universe became transparent to electromagnetic radiation. Its temperature then was 2970 K. What was the wavelength at which the background radiation was then most intense?
