onda radio
Lemma: onda radio
Translation: radio wave (noun)
Etymology: The term 'onda radio' combines 'onda' (wave) from Latin 'unda' (wave, ripple) and 'radio' which derives from Latin 'radius' (ray, beam). The term describes electromagnetic waves used for wireless communication. The Latin 'unda' is also the root of English words like 'undulate' and 'inundate', while 'radius' gives us English words like 'radiate' and 'radiation'.
