# 6 Wave equation in spherical polar coordinates

6 Wave **equation in spherical** polar **coordinates** We now look at solving problems involving the Laplacian **in spherical** polar **coordinates**. The angular dependence of the solutions will be described by **spherical** harmonics. We take the wave **equation** as a special case: ∇2u = 1 c 2 ∂2u ∂t The Laplacian given by Eqn. (4.11) can be rewritten as: ∇ ...

(10) is an important result and is used frequently in **electromagnetism**, uid mechanics, and other ‘ eld theories’. Finally, when a scalar eld ˚depends only on the magnitude of the position vector r= jrj, we have r2 ˚(r) = ˚00(r) + 2˚0(r) r where the prime denotes di erentiation with respect to r. Proof of this relation is left to the ...
