Why is it termed "SHORT" WAVE ?

Because it is shorter than medium wave, which in turn is shorter than
long wave - back when these types of radio signals were the commonly
used wavelengths.

Of course, now with microwaves and picowaves, the name becomes much
less meaningful. In fact, the term H(igh) F(frequency), which seems to
have replaced SW for many purposes, is not really accurate either.

Very good Bruce -- indeed it is an ancient term carried over to this very
day

From Wikipedia or google


Shortwave radio operates between the frequencies of 3,000 kHz and 30 MHz
(30,000 kHz) and came to be referred to as such in the early days of radio
because the wavelengths associated with this frequency range were shorter
than those commonly in use at that time. An alternate name is HF, or high
frequency.
