Article description: (description)
This attribute controls the content of the description and og:description elements. | In physics, the plane-wave expansion expresses a plane wave as a linear combination of spherical waves:
$ {\displaystyle e^{i\mathbf {k} \cdot \mathbf {r} }=\sum _{\ell =0}^{\infty }(2\ell +1)i^{\ell }j_{\ell }(kr)P_{\ell }({\hat {\mathbf {k} }}\cdot {\hat {\mathbf {r} }}),} $
where
i is the imaginary... |
