This lecture (2 parts, this part 2) considers Thomson, Rayleigh, and resonant line scattering as a classical, driven and weakly damped, oscillator. This part is about spectral line scattering, introducing also Lorenz profile function, FWHM, and the extreme "Quality" (Q-value) of this resonance. Explains also why we use terminology like "resonance lines" and "oscillator strengths".
Course: Radiation Processes in Astronomy

I record lectures live and place them here un-edited, in the hope that it will provide a more authentic feeling of the sort: "we're doing the actual work here and now". So like I keep telling students in the classroom: whenever you discover me doing some error let me know directly; for this channel this means make a comment on the videos. Then we can have a look at it, and thereby learn nicely from each other as we continue to develop our knowledge.
