Morphology

infrared = red (transparent) = infra + red

Clear prefixation from 'red' by the combining form 'infra-', producing the adjectival meaning 'beyond/below red' on the spectrum.

Etymology

Infrared comes from the Latin prefix infra- meaning 'below' and the color red. So when something is described as infrared, it uses light 'below red', that is, light with longer waves than the red we can see.
