espectro
spectrum
noun ehs-PEHK-troh Rare
Origin: Latin spectrum (appearance, image)
Also means
ghost
Usage Note
Espectro has two distinct uses: the scientific meaning (electromagnetic spectrum, light spectrum) and the literary/colloquial meaning of a ghost or spectre. Context usually disambiguates. In medical Spanish, espectro autista (autism spectrum) is the standard clinical term, not a calque but the accepted translation.
Examples
"La luz blanca contiene todo el espectro visible."
Natural Translation
White light contains the entire visible spectrum.
