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)
