Relation To Planck's Law
The Wien approximation was originally proposed as a description of the complete spectrum of thermal radiation, although it failed to accurately describe long wavelength (low frequency) emission. However, it was soon superseded by Planck's law, developed by Max Planck. Unlike the Wien approximation, Planck's law accurately describes the complete spectrum of thermal radiation. Planck's law may be given as
The Wien approximation may be derived from Planck's law by assuming . When this is true, then
and so Planck's law approximately equals the Wien approximation at high frequencies.

Famous quotes containing the words relation to, relation and/or law:
“The difference between objective and subjective extension is one of relation to a context solely.”
—William James (18421910)
“There is the falsely mystical view of art that assumes a kind of supernatural inspiration, a possession by universal forces unrelated to questions of power and privilege or the artists relation to bread and blood. In this view, the channel of art can only become clogged and misdirected by the artists concern with merely temporary and local disturbances. The song is higher than the struggle.”
—Adrienne Rich (b. 1929)
“They who say that women do not desire the right of suffrage, that they prefer masculine domination to self-government, falsify every page of history, every fact in human experience. It has taken the whole power of the civil and canon law to hold woman in the subordinate position which it is said she willingly accepts.”
—Elizabeth Cady Stanton (18151902)
