>>7618726>>7619031I think I can explain it in a sort of acceptable manner. I'll try and chuck in historical context as I go along.
Back in Ye Olde Days there were a few theories going around about the nature of the universe, Classical Mechanics and Electromagnetism being amongst the principal ones and what we are concerned with.
Now, Classical Mechanics pre-dated Electromagnetism by many years. And about the same time as its inception, one of the guiding assumptions in Physics was made i.e. 'The laws of physics are the same in all inertial frames'.
What this means is that if you are moving at some constant velocity and someone else is moving at a constant velocity then nothing you do will reveal a difference in the laws of physics from your respective viewpoints.
This seems perfectly reasonable. After all, we want our laws to hold for everyone no matter what speeds they're going at, or where they are. Otherwise they wouldn't really be laws, they'd just be local patterns.
Fast forward about two centuries later to the emergence of electromagnetism. James Clerk Maxwell appears as the culmination of decades of work in bringing the once separate fields of electricity and magnetism together and formulates his four equations, one of which is where and are constants. Out of these equations popped out these terms which happens to be very similar to the form of a wave equation .
In other words, term represents that term in an electromagnetic wave equation.
