will close #95

Is this part OK?

the incident radiation can be considered to be monochromatic

I'm thinking about a case like having a tube source and a Johannson mono, where the emission profile is some funky thing that still requires multiple wavelengths to model properly, but is "monochromatic". or even a curved graphite mono where there is still some residual kB radiation; i'd still call that "monochromatic", but it has been refined.

I think what @rowlesmr has written is not bad. I considered "in cases where the incident spectrum can be modelled as one or a few discrete wavelengths" but then that has its own problems as the spectra you show are continous.
