Noun

shortwave (plural shortwaves)

1. (physics) An electromagnetic wave having a wavelength between approximately 10 and 100 meters, corresponding to frequencies between 3 and 30 MHz.

   Shortwaves are longer than microwaves.

2. (colloquial, usually in the plural) Any frequency in this range, especially when used in broadcasting.

   Many stations broadcast on shortwaves.
