Definition It is the result of a mixture of radiation from many independent sources, such as stars and galaxies that formed within the first billion years of the Big Bang.
You are exposed to nuclear radiation everyday. A) It has a temperature of about 3 degrees K above absolute zero. The cosmic microwave background is radiation left over from the big bang. The redshift of light emitted by most galaxies indicates the universe is expanding. It is the result of a mixture of radiation from many independent sources, such as … C. Naturally occurring nuclear radiation is called background radiation. As the theory goes, when the universe was born it … The cosmic microwave background temperature is 2.73 K. 6. The cosmic microwave background (CMB) is thought to be leftover radiation from the Big Bang, or the time when the universe began. Researchers found the "cosmic microwave background radiation", which is a heat imprint left over from the big bang. The helium abundance is at least 25% in every galaxy studied so far. Photons of the cosmic microwave background have traveled through space for almost 14 billion years. A. 7. Most of the nuclear radiation you are exposed to occurs naturally in the environment.

The CMB is visible at a distance of 13.8 billion light years in all directions from Earth, leading scientists to determine that this is the true age of the Universe. f the following are true of the True False fills the entire Universe today has a temperature of -3000 K comes from all directions discovered in the 1960s with a radio telescope consists of many spectral emission lines

5. The Cosmic Microwave Background radiation, or CMB for short, is a faint glow of light that fills the universe, falling on Earth from every direction with nearly uniform intensity. asked Sep 24, 2016 in Physics & Space Science by craftychris. Which of the following does not provide strong evidence for the Big Bang theory? 2. D. All natural radiation is at a level low enough to be safe.

Question 20 of 23 Mapo Sapling Learning macmillan learning Which of the following are true of the cosmic microwave background radiation (CMB) and which are false? Which of the following statements about the cosmic background radiation is not true? Inference: 1. observations of the amount of hydrogen in the universe : Which statement about the cosmic microwave background is NOT true? Which of the following statements is NOT true? B. B) It appears essentially the same in all directions (it is isotropic).
It is the result of a mixture of radiation from many independent sources, such as stars and galaxies that formed within the first billion years of the Big Bang.
