Why is it important to continue to study electromagnetic waves?

Answer 1

Though we know a great deal about electromagnetic (em) waves, there are still more things to learn. Our grasp of a solid body of knowledge of em waves is showcased by our use of electricity, and, in particular, our use of electronic gadgets and equipment. We're down with a lot of stuff, and we got tools and toys to prove it. But we still have things to learn. There remain some fundamental questions regarding some of the more subtle aspects of the working of electromagnetic waves. Here's a simple example: superconductivity. It was first discovered by Heike Kamerlingh Onnes in 1911. That's almost a hundred years ago! And do we know how superconductivity works? Nope. We're still scratching our heads. Einstein published E=mc2 in the early 1900's and we had the bomb about 50 years later. And with a simple little phenomenon like superconductivity, we still don't know how it works almost a century later. There's still work to do as regards our investigation into how electromagnetic waves work. Wouldn't you agree?
