Cosmic background radiation, Physics

Assignment Help:

Cosmic background radiation; primal glow

The background of radiation typically in the frequency range 3 x 1011 to 3 x 108 Hz discovered in space in the year of 1965. It is supposed to be the cosmologically redshifted radiation free through the big bang itself. Currently it has an energy density in empty space of about 4 x 10-14 J/m3.
