How does electromagnetic energy differ from other energy sources?

Answer 1

It travels very fast (at the speed of light) and requires no wires (or any medium) to be transferred.

The most common energy source is probably electricity (technically a secondary energy source since it is derived from other sources) but it serves the purpose here as you can see that it requires infrastructure to transport it (wires) and it moves at about 1/3 the speed of light.

E-m radiation can travel through a vacuum (e.g. the Sun illuminates the earth through the vacuum of space.)

Electromagnetic energy differs from other energy sources in that it is a form of energy associated with the electromagnetic force, encompassing a wide range of frequencies including visible light, radio waves, microwaves, X-rays, and gamma rays. Other energy sources, such as thermal energy, mechanical energy, chemical energy, and nuclear energy, arise from different physical processes or interactions.

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.
