The cosmic microwave background (CMB) matches a 2.7 K blackbody spectrum extremely well. For a space telescope observing the CMB with an efficient detector with a collecting area of 0.01 m2, estimate (i) the wavelength at which the CMB peaks in intensity, (ii) the power in watts of CMB photons collected by the detector and (iii) the number of CMB photons per unit volume in the vicinity of the space telescope.

The cosmic microwave background CMB is a primordial glow of electromagnetic radiation which comes to us with almost equal intensity from every direction in the sky. The CMD shows a characteristic pattern of very finite bright and dim patches with a typical patch separation of 1° we would like to patch a telescope that can resolve these bright and dim patches distinguish two sources in the sky separated by 1° suppose that we build our telescope to measure the CMB...

We often say that the cosmic microwave background radiation (CMB, or CBR) is a direct viewing of the Big Bang. But actually, the temperature of this black-body radiation (3 degrees K) is insanely low for the Big Bang. Why is it so low, when the Universe started out so hot? And why do we say now that the CMB represents light from about 400,000 years after the Big Bang, rather than the Big Bang itself?

(c) Why are these results from part (b) important?

16. The cosmic microwave background radiation (CMB) is radiation that bathes the Universe from every direction, and appears to be emitted by a blackbody at a temperature of 2.7 Kelvins. This radiation a. comes from stars. b. comes from supernovae. c. is the redshifted glow of the hot young universe, appearing much cooler today. d. consists of cosmic rays emitted by dying stars.
