A question about the EM spectrum

[Sundown444]

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.

So, just to make sure, is this actually legit, or is it fake? I am curious.

Terrahertz Radiation is a real part of the spectrum.

Okay then. Just wanted to make sure. Thanks. I asked some other guy and he said it was just a frequency. Apparently, he did not know about the radiation.

Say, when was Terahertz radiation labeled as part of the EM spectrum?

Look at the second paragraph of the wiki link - especially the parts on electromagnetic spectrum and electromagnetic radiation.

I was looking for an exact year. Based on what I have read, was it labeled within the last two years?

EDIT: Never mind.

Confused "harnessing the spectrum" with knowing it's there?

It's okay. I got it.
