Sorry this isn't math .

Question

Sorry this isn't math >.<

I have a good understanding but I'm lost on how to answer it. 

In your own words, explain why the direction along which the electromagnetic wave travels is not the same as the direction along which the changing electric field is applied.

I did.

Do you mean the equipotential lines? The electric field is perpendicular to those lines (90 degrees), because the direction of the electric field has to be in the direction of the electric force that would act on a certain charge q placed in a field. The equipotential lines indicates the location of all points having the same electric potential (constant voltage V). |dw:1389760552763:dw|
