I was looking around for information on the electromagnetic spectrum, but I have found some sources saying there is a new part of it called "terahertz", which would be between infrared and microwave. I have found some sources, but I don't really believe them so. Here are some sources of what I found. http://www.lightsources.org/terahertz-radiation-or-t-rays http://www.teraview.com/about/what-is-terahertz-thz.html http://www.teraphysics.com/understanding-thz.php [Broken] http://www.dlr.de/pf/Desktopdefault.aspx/tabid-833/1333_read-2400/ So, just to make sure, is this actually legit, or is it fake? I am curious.
