Wien’s displacement law
For an ideal blackbody, the wavelength at which emission peaks shifts toward shorter wavelengths as temperature rises.
Formula usedλmax T = b

Example 2
At 300 K, the peak is near 9.66 µm, in the infrared.
Good to knowThis is Wien’s law for an ideal blackbody spectrum. Real objects may depart from an ideal blackbody.
