- What is the energy in joules of a proton with a wavelength of 7.50 x 10^-5m?As noted in the chapter, the cosmic microwave background radiation fits the Planck equation for a blackbody at 2.7 K. (a) What is the wavelength at the maximum intensity of the spectrum of the background radiation? (b) What is the frequency of the radiation at the maximum? (c) What is the total power incident on Earth from the background radiationWhy does the cosmic microwave background (CMB) shine in low-energy microwave wavelengths? O The trapped photons within the plasma of the earliest universe originally had wavelengths in the microwave band due to rapid inflation O The CMB was originally emitted as high-energy gamma rays and x-rays, but the light has redshifted downward to lower-energy microwaves through time When nuclei of H and He first combined with free electrons to create atoms, photons of light were released as microwaves The photons released in the CMB were intensely hot, with energy levels in microwave wavelengths The early universe 380,000 years after the Big Bang was cold (2.7 kelvins) the temperature of microwave energy
