I've been stuck trying to figure out what's going on in a particular section of my notes for the last couple days. The biggest issue is the lecturer has just not explained where the example has come from and what it represents. I thought I would post the relevant section here and see if anyone could recognise it immediately. He just introduced the 3D wave equation which I understood but then stated the case of spherical symmetry without any explanation. I was wondering why he defined Ψ in the manor he did and had no clue why he involved an angular section. Does anybody know what's going on? The note section is attached
