What will the temperature of the cosmic microwave background be when the average distances between galaxies are 1.7 times as large as they are today? (Hint: The peak wavelength of photons in the background will then also be 1.7 times as large as it is today.)

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?
