Clarification of Naming conventions used in naming different parts of the EM spectrum

According to the Microwaves page, Microwaves are 300MHz-300GHz. I think that it would be good for wikipedia to be self-consistent in its naming convention for different parts of the Electromagnetic spectrum. Including a table of references for different conventions (if necessary to help researchers, etc... navigate different conventions) might be a good idea, if the historical evolution of EM naming conventions has been such.

Actually the Microwave article (and its sources) says there is no consensus on where the lower boundary of the microwave band is, different sources regard microwaves as beginning at 300 MHz to 3 GHz. Although I don't really think it is important, I edited the article to be be consistent with that. --Chetvorno^TALK 21:29, 26 February 2018 (UTC)

Microwave photon

I was looking into microwave photons today, and found this article by an astrophysicist/professor (Brian Koberlein), written in everyday language. Just how big is a photon. It might be helpful to anyone looking into the topic. ("It’s a bit odd to think of a microwave photon as being larger than a baseball, but it is a simple way to explain how mesh reflectors work."

The image being shown with this article (today) is *really* helpful in visualizing how radio 'photons' are generated. One 'microwave photon' is *much* lower in energy than a light photon, so *many more* of them are needed to deliver the same energy. (More on that here, discussing microwave ovens.)

A much more 2008 technical article here titled "Generating Single Microwave Photons in a Circuit" describes an interesting application. Twang (talk) 22:43, 10 January 2019 (UTC)

Tune it down

The animation is a bit much, as its large and distracting from readability. -Inowen (nlfte) 08:46, 21 January 2019 (UTC)

New inventor of radio device. Really?

Someone edited the article claiming original invention of radio devices by an indian scientist, instead of Marconi, without providing any source. 191.106.200.16 (talk) 00:40, 1 November 2022 (UTC)

 Reverted. Thanks! --Chetvorno^TALK 06:41, 1 November 2022 (UTC)

Wave length?

Here, you describe the wavelength of radio waves as "wavelengths greater than 1 millimeter...the diameter of a grain of rice" but under your entry for the electromagnetic spectrum, radio wavelengths are described as "the longest wavelengths—thousands of kilometers, or more". Perhaps technically "greater than" 1mm can include "thousands of kilometers" but there is nothing in this entry to indicate that radio waves can be that long. Another source on radio wave length describes them as ranging "from a few millimeters to hundreds of kilometers". The wiki entry on the electromagnetic spectrum even includes an aid "approximate scale of wavelength" where it puts radio wave lengths at the size or scale of "buildings" with infrared waves at the scale of "needlepoint" or much closer to your "grain of rice". Am I misunderstanding something, or are these two entries in disagreement as much as they appear to be? RPeel (talk) 07:55, 10 July 2026 (UTC)
