The universe is filled with thermal radiation, which has a blackbody spectrum at an effective temperature of $2.7 \mathrm{~K}$ (see Chapter 15 ). What is the peak wavelength of this radiation? What is the energy (in eV) of quanta at the peak wavelength? In what region of the electromagnetic spectrum is this peak wavelength?
