First line suggests frequency range of 1000 MHz to 300 GHz. Inconsistent units are unhelpful. Suggest change to

...1 GHz to 300 GHz. 144.32.240.36 (talk) 17:06, 6 November 2023 (UTC)[reply]

I'm not particularly opposed to this change, as people unfamiliar with metric prefixes could get confused, but I noticed that this particular sentence has six inline citations right now, which looks suspiciously like WP:CITEOVERKILL (surely one or two citations would be enough to support a simple statement like this?). I haven't found any evidence, but I wonder if there was once a dispute over this statement. Liu1126 (talk) 17:32, 6 November 2023 (UTC)[reply]

 Done the edit as requested. No comment on the citation overkill. Maproom (talk) 18:29, 6 November 2023 (UTC)[reply]

In the History section, can we have consistency when mentioning the early inventors nationalities? Either add the nationality of all mentioned or remove them. There is a German physicist, Indian physicist and a Russian physicist. No mention of Maxwell, Lodge and Rayleigh being British and Righi being an Italian physicist.

Bose was in fact British Indian and in modern terms he would be classed as Bagladeshi not Indian.

Line: "The main effect of absorption of microwaves is to heat materials; the electromagnetic fields cause polar molecules to vibrate."

Heating is far from the "main effect" of microwaves, just one effect of many that microwaves have on molecules. Just because microwaves are most well known in the public conscience in the form of microwave ovens does not make this the most important thing. Further, microwaves cause a rotational excitation of molecules, not a vibrational one-- vibration is caused by IR.

Suggested: "Absorption of microwaves heats materials by transferring energy to the molecules, causing them to rotate. Orisgeinkras (talk) 01:41, 1 September 2024 (UTC)[reply]

Needs a WP:RS for the rotational effect. Zefr (talk) 02:27, 1 September 2024 (UTC)[reply]

 Not done - this issue was addressed at Talk:Microwave oven, here. Zefr (talk) 16:11, 1 September 2024 (UTC)[reply]

Agree with Zefr and Talk:Microwave oven, the word "rotate" would be misleading for readers. And heating (molecular motion) is clearly the main effect of microwaves, so I am okay with the sentence in question.

Should we maybe address Orisgeinkras's issue by adding an additional sentence such as: "The main way microwaves heat substances is by exciting the rotational energy levels of polar molecules"

Here's a citation: "It is the ... rotation of molecules which have characteristic frequencies so low that they lie in the microwave range and dominate microwave spectra" Townes, Schawlow (1975) Microwave Spectrometry, p.2
