I apologize for not following the template, but it doesn't really fit. I would have posted it elsewhere but as it's for academic purposes I think it has to be here. Please excuse me if I'm wrong. I'm a high schooler working on a project, and I was planning to send ≈3 cm microwaves through an ice sphere with diameter varying from about 1-6 cm and see the change in scattering. Unfortunately, through the research I've done it seems like this is way more complicated than I'd imagined. So, I need some help. Wikipedia (Most reliable source... Well...) states: And this confuses me. I know ice absorbs some EM waves, and thus it must be somewhat inelastic. However, I'm not sure whether that's what is meant. Can someone help me with which I should use, and why?
