The cosmic background radiation is blackbody radiation from a source at a temperature of 2.73 K. (a) Use Wien’s law to determine the wavelength at which this radiation has its maximum intensity. (b) In what part of theelectromagnetic spectrum is the peak of the distribution?
Using Wien's Law for two black body objects with a temperature of 1000 K (fire) and 290 K (background), at what central wavelengths are the two objects radiating?
According to Wien's Displacement Law, the wavelength of maximum emission of a body with a temperature of 357 Kelvin would be:
