What is spectral distribution of cosmic microwave background radiation?
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.
Cosmic microwave background radiation found uniformly spread throughout the universe is supposed to be what?
Cosmic Microwave Background Radiation is electromagnetic radiation left over from the events of the Big Bang. This radiation causes a very slight increase in the universe's temperature; the coldest areas of the universe will be only about 2 degrees kelvin (2 degrees above absolute zero). It is not spread in a perfectly uniform pattern, though the differences in density are very slight.
Where in the world is Cobe to be found?
COBE or the Cosmic Background Explorer is a satellite which is dedicated to cosmology. It was aimed at investigating cosmic background microwave radiation and help to improve our general understanding of the universe.
What heat transfer uses electromagnetic waves to increase thermal energy?
Microwave Radiation is Very Effectively absorbed by Water molecules, this results in the increased thermal agitation of the Water molecules that absorb the Mw radiation - as found in Microwave ovens.
What is the background noise of the big bang theory?
The Cosmic Microwave Background Radiation was predicted by proponents of Big Bang Cosmology (BBC) about 18 years before it was found. Its existence, isotropy, and spectrum is easy to explain with BBC; pretty much impossible to explain using alternatives.

Is there any radiation from the mobile tower which will affect the human lives?
Basically no. Microwave radiation only has the effect of heating things up (think of the microwave in your kitchen). There has been some debate whether this could heat up your brain and what effects it would have, but it has generally found to have little or no effect.

Does an incubator machine uses radiation?
Most incubator machines use no forms of radiation as it can be found harmful, instead they usually use an array of special lamps.
What are low energy waves found in electromagnetic spectrum called?
Low energy waves found in the electromagnetic spectrum are called radio waves. They have longer wavelengths and lower frequencies compared to other forms of electromagnetic radiation. Radio waves are commonly used in communication technologies such as radio broadcasting, television broadcasting, and wireless networking.
What is the leftover thermal energy from the big bang?
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.
Energy that travels by radiation is often called what?
When we use the term "radiation" as regards energy, probably the first thing that comes to mind is electromagnetic energy. Electromagnetic (EM) energy is often called electromagnetic radiation. We know that this could be radio waves, microwave energy, infrared light, light from the visual spectrum, ultraviolet light, X-rays or gamma rays. All of these are forms of electromagnetic radiation, and a link can be found below for more information.Radiant energy.

What radiation type has no charge?
Neutrons are the radiation type that has no charge. They are neutral particles found in the nuclei of atoms and can penetrate matter more easily compared to charged particles due to their lack of electromagnetic interaction.
What heat transfer uses electromagnetic waves to increase thermal energy?
Microwave Radiation is Very Effectively absorbed by Water molecules, this results in the increased thermal agitation of the Water molecules that absorb the Mw radiation - as found in Microwave ovens.
Who were the two scientists that discovered CBR and how did they discover it?
The Cosmic Microwave Background Radiation (CBR) was discovered by Arno Penzias and Robert Wilson in 1965. They were working on a radio telescope and found an unexpected source of noise that turned out to be radiation left over from the early universe, providing evidence for the Big Bang theory.
How is the use of radioactive isotopes in treating some forms of cancer related to certain properties of gamma radiation?
Gamma rays emitted by the radioisotope cobalt-60 have been found to be very effective in treating some forms of cancer.
