## small angle light scattering

What about small angle light scattering? The theory is exactly the same. As the title of Kerker's boook (The scattering of light and other electromagnetic radiation) makes clear. It's just a question of the accessible length scales, depending on q. A table comparing the ranges of q accessible by the three techniques would be useful.

## Theory - Continuum description

In the first and second sentence in "Theory - Continuum description" section there is the equation "${\displaystyle q=4\pi \sin(\theta )/\lambda }$" and it continues as "here ${\displaystyle 2\theta }$ ...". Is a ${\displaystyle 2\theta }$ missing from the first equation? If not then what does ${\displaystyle \theta }$ represent? I am not sure if it is wrong or not well explained. — Preceding unsigned comment added by Elefand (talkcontribs) 19:07, 1 March 2015 (UTC)
