Wein's Law The wavelength of the peak emission for a blackbody is given by Wein's law (Eq 1.0.1), also known as Wein's
displacement law.
Amax = a / T
Eq (1.0.1)
Where Imax is the peak emission wavelength in um, a is a constant that equals 2897 um•K, and T is the
blackbody temperature.
The star Fomalhaut, some 25 light-years distant, has a surface temperature of 8590 K. What is the peak
emission wavelength for Fomalhaut?
