Wien’s Law
qWien’s law relates an objective’s maximum emitted wavelength of radiation to the
objective’s temperature.
qIt states that the wavelength of the maximum emitted radiation by an object is inversely
proportional to the objective’s absolute temperature.
lmax = w/T
lmax = wavelength (micrometers)
W = 2897 mm K
T = temperate (K)
