(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I am given a plasma at 8000 Kelvin and assume its an ideal blackbody. I have slit of 0.01 cm^2, observing at wavelength 325 nm with a spectral bandwidth of 0.05 nm.

The problem asks that the actually continuum under these conditions is 1 pW. What is the emissivity?

2. Relevant equations

Planck's curve

3. The attempt at a solution

I do not know how to treat a continuum when before I was looking at a particular bandwidth.
