Question:

(a) What is the spectral radiant emittance of a \(1000 \mathrm{~K}\) blackbody in the region of \(2 \mu \mathrm{m}\) wavelength?

(b) What is the radiance?

(c) If an idealized band-pass filter only transmitting between 1.95 and \(2.05 \mu \mathrm{m}\) is used, what is the total power falling on a \(1 \mathrm{~cm}^{2}\) detector placed \(1 \mathrm{~m}\) from a \(1 \mathrm{~cm}^{2}\) blackbody?
