Cosmic background radiation. The following figure shows measurements of the energy density of the background cosmic radiation. The graphical quantity is the spectral density as a function of the energy per unit volume according to the relationship: di / dw = cu(w) / 41 Assuming Planck's Law, estimate the temperature of the background cosmic radiation. Use that lerg = 10-7 J, kg = 1.38 x 10-23 J/K y c~ 10%m/s. -3.00 30 Wavelength (cm) 0.3 0.03 10-14 10-15 10-16 10-17...
In 1965 Penzias and Wilson discovered the cosmic microwave radiation left over from the Big Bang expansion of the universe. The energy density of this radiation is 7.62
Please answer and explain 15. (4 points) The microwave radiation left over from the Big Bang explosion of the universe has an average energy density of 4*10 J/m. What is the rms value of the electric field from this radiation? Equation (s) to use Final Solution:
Cosmic microwave background radiation fills space with an average energy density of about 4
Please make sure you give me the correct answer 13) The cosmic background radiation permeating the universe has the spectrum of a 2.7-K blackbody radiator. The energy density of deep space is 4.19 x 10-8 J/cm3 a, What is the peak wavelength of this radiation? b, Assuming the energy density of space is from these photons, how many photons are there on average in each cubic centimeter of space?
The "classic" Big Bang theory explains that the Universe was originally very hot and very dense and that this leads to some clear predictions that have been experimentally verified.However, there were some observed properties of the Universe that the classic Big Bang theory couldn't explain. Explaining these additional properties of the Universe required the development of the model of cosmic inflation in the 1980s, which has some additional predictions we are attempting to verify with experiments today. What properties of...
The cosmic background radiation permeating the universe has the spectrum of a 2.7-K blackbody radiator. What is the peak wavelength of this radiation? The constant in Wien's law is 0.0029 m ∙ K. Hint: the answer will be in mm
1. Consult Multiple-Concept Example 5 to review the concepts on which this problem depends. A light bulb emits light uniformly in all directions. The average emitted power is 150.0 W. At a distance of 6 m from the bulb, determine (a) the average intensity of the light, (b) the rms value of the electric field, and (c) the peak value of the electric field. 2. On a cloudless day, the sunlight that reaches the surface of the earth has an...

(10.6) The typical energy of a neutrino in the Cosmic Neutrino Background as ported out in Chapter 5, is E,, ~ kT,, ~ 5 × 10-4 eV. What is the approximate interaction cross-section ơw for one of these cos- mic neutrinos? Suppose you had a large lump of 56Fe (with density p 7900 kg m. What is the number density of protons, neutrons, and electrons within the lump of iron? How far, on average, would a cosmic neutrino travel through...
