short waven.

Forms: Also ˈshort-wave, shortwave.

Etymology: < short adj. + wave n.

a. An electromagnetic wave of relatively short wavelength, spec. a radio wavelength of less than about 100 metres, corresponding to a frequency of more than 3000 kilohertz; radio communication or broadcasting employing such waves. Usually attributive or as adj. ; also in adverbial use.
