Definitions for "Wien's law"
An experimentally discovered law applicable to thermal continuum radiation, which states that the wavelength of maximum emission intensity is inversely proportional to the absolute temperature.
This radiation law suggests that the wavelength of maximum emission of any body is inversely proportional to its absolute temperature. The following equation mathematically describes this law: max = / where max is the body's maximum emitted wavelength of radiation in micrometers (µm), is a constant equal to 0.2897, and is the temperature of the body in Kelvins.
Relation which gives the connection between the wavelength at which a black-body curve peaks and the temperature of the emitter. The temperature is inversely proportional to the peak wavelength, so the hotter the object, the bluer its radiation.
