How do electromagnetic waves transfer energy?
The key to understanding how electromagnetic energy gets transfered into materials is in understanding the sites in the material that will respond to the EMR. This is quantum mechanical stuff, pure and simple. But it really doesn’t take an advanced degree to get a handle on it. It breaks down in a way that we can wrap a brain cell around it without any advanced mathematics. We’ll add some links in case you feel like exploring. You’ll find them below.
