Neptune and Wien's Law
Name: Robert W.
Can the temperature of clouds on Neptune be measured
using Wien's Law? As an example, if the maximum wavelength of emission
from Neptune's clouds is 6.0 x 10 Exp-5 would the Temperature be
48.33K? Or does the blackbody principle requirement of Wien's Law not
work in this case?
More likely the distribution of frequencies would be fitted to Planck's
radiation formula to obtain a more accurate measure of the average
temperature. But what one obtains is a temperature averaged over the entire
field of view.
