The measurements at a number of discrete frequencies of the background radiation that fills space
place their relative amplitudes reasonably close to the curve that characterizes the radiation of a
blackbody with a temperature of 2.725 degrees absolute. As such, the peak amplitude is found
at the frequency of about 162.5 GHz.
Cosmic rays are not part of the EM spectrum -- they are high energy charged particles.
The spectral distribution of cosmic microwave background radiation follows a blackbody spectrum with a temperature of approximately 2.7 Kelvin. It peaks in the microwave region of the electromagnetic spectrum, with a characteristic wavelength of around 1 mm. This radiation is considered a key piece of evidence supporting the Big Bang theory.
the weakness of cosmic back ground radiation as those radiation are left over of big bangs
Primordial background radiation is in actuality Cosmic Microwave Background. To discover just what Cosmic Microwave Background theories are, visit the URL posted below:http://www.astro.ucla.edu/~wright/CMB.html
The cosmic background radiation is believed to be the remains of the radiation emitted by the Universe when it started to get transparent - when it had cooled down to a temperature of about 3000 kelvin.
The big bang caused the background radiation.
The leftover thermal energy from the Big Bang is known as the cosmic microwave background radiation (CMB). It is a faint glow of radiation that permeates the universe and is considered a remnant from the early universe when it was much hotter and denser. The CMB provides important clues about the early universe's properties and evolution.

The cosmic background radiation is believed to be the remains of the radiation emitted by the Universe when it started to get transparent - when it had cooled down to a temperature of about 3000 kelvin.
The cosmic background radiation was discovered in 1964 by American radio astronomers Arno Penzias and Robert Wilson
Then it will not emit any more radiation - except that it will eventually re-emit any radiation it receives, especially the cosmic background radiation.Then it will not emit any more radiation - except that it will eventually re-emit any radiation it receives, especially the cosmic background radiation.Then it will not emit any more radiation - except that it will eventually re-emit any radiation it receives, especially the cosmic background radiation.Then it will not emit any more radiation - except that it will eventually re-emit any radiation it receives, especially the cosmic background radiation.
