It's not exactly a problem. I was wondering if anyone could explain in the most basic terms what it is, what are its' uses and where is it found. I've done a little research, but haven't been taught what it does so it's kind of hard to understand what it does. Is it true that it is used to study the nature of matter and energy? What do scientists get or discover by doing this? Also, is it found in x-ray generators and television sets? Is it found in any other basic every day objects? Thanks.
