Electromagnetic energy travels in the form of waves. These waves consist of electric and magnetic fields oscillating perpendicular to each other and perpendicular to the direction of wave propagation. They can travel through a vacuum, such as outer space, as well as through various materials, including air, water, and solids.

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.
