Microwaves, also known as Super High Frequency (SHF) signals, have
wavelengths
approximately in the range of 30 cm (1 GHz) to 1 mm (300 GHz).


if all microwaves are SHF, then there isn't any microwave oven that I know of
that actually uses microwaves. So why call it a microwave oven?

SHF starts at 3 GHZ (300 MHZ), not at 1 GHZ (100 ghz).

I've read that most microwave ovens operate in or around the 2.4 GHZ band
(which is UHF, not SHF).

Remember "Radar Ranges"?

Why is the sonicare toothbrush so called, except to attempt a
connection with true ultra-sonic cleaners and the way they work?

Excerpt from the site below:

The first Raytheon commercial microwave oven was the 1161 Radarange, which
was marketed in 1954. Rated at 1600 watts, it was so large and expensive
that it was practical only for restaurant and institutional use.
In 1967, Amana, a division of Raytheon, introduced its domestic Radarange
microwave oven, marking the beginning of the use of microwave ovens in home
kitchens. Although sales were slow during the first few years, partially due
to the oven's relatively expensive price tag, the concept of quick microwave
cooking had arrived. In succeeding years, Litton and a number of other
companies joined the countertop microwave oven market. By the end of 1971,
the price of countertop units began to decrease and their capabilities were
expanded.

No, you remember the Amana Radarange being advertised.
