What are some uses of electromagnetic energy?
There are many diverse uses.
From cosmic rays to radio waves, the electromagnetic spectrum encompasses a vast range of frequencies. Its applications are diverse; for example, gamma rays are used to eradicate tumors, microwaves are used for heating, visible light is used to see, and radio waves are utilized for radio channels.

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.
