The blackbody in Problem 10 is a large isothermal enclosure.
A small object is now placed inside this enclosure. Find the irradiation
incident on this object.

Problem 10

A blackbody is radiating at a constant temperature of 2500
K. Find a) the emissive power of radiation from this blackbody, b) the
wavelength below which 15% of he radiation of the blackbody is concentrated, c)
the wavelength above which 10% of the emission is concentrated, d) the maximum
spectral emissive power, e) the wavelength associated with the maximum spectral
emissive power.
