[QUOTE="schrodingerscat11, post: 4946008, member: 344384"] [h2]Homework Statement [/h2] Hi! There is a formula in Griffiths that relates the electric field and the magnetic field: [itex]\mathbf{\tilde{B}}(\mathbf{r},t)=\frac{1}{c}\mathbf{\hat{k}}\times\mathbf{\tilde{E}}[/itex] Question: Is this formula applicable for plane waves only? Can I use this for spherical waves? Thank you very much. [h2]Homework Equations[/h2] See above. [h2]The Attempt at a Solution[/h2] I was told this is just for plane waves, but I want to be sure. Thank you! :) [/QUOTE]
