Discussion Overview

The discussion revolves around the classification of terahertz radiation within the electromagnetic spectrum, exploring its legitimacy and historical context. Participants express curiosity about whether terahertz is recognized as a distinct part of the spectrum and seek clarification on its classification timeline.

Discussion Character

  • Exploratory
  • Debate/contested

Main Points Raised

  • Some participants assert that terahertz radiation is a legitimate part of the electromagnetic spectrum.
  • One participant questions the historical labeling of terahertz radiation, seeking an exact year for its classification.
  • Another participant references external sources to support their inquiry about terahertz radiation.
  • There are repeated requests for clarification regarding the status of terahertz radiation, indicating some uncertainty about its recognition.

Areas of Agreement / Disagreement

While some participants agree that terahertz radiation is a real part of the spectrum, there remains uncertainty about its historical classification and the exact timeline of when it was recognized as such.

Contextual Notes

Participants express confusion over the distinction between recognizing terahertz radiation as part of the spectrum and the practical applications of harnessing it. There is also a lack of consensus on the specific timeline for its classification.

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.

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? :oldsmile:

It's okay. I got it.
