How do electromagnetic waves travel?
Piper HoffmanI have a nice picture to show a perturbation of the Electric Field, produced by an accelerated charge, propagating outwards:
I got this amazing picture from my old Physics book (Ohanian Physics):

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
