It is not a coincidence that this happens in the "visible range," as the mechanism of vision involves the change in bonding of a single molecule (retinal) which absorbs light in the rhodopsin in the retina of the human eye.
Non é casualidade que isto ocorra no "alcance visible", xa que o mecanismo de visión implica o cambio no enlace dunha única molécula (retinal) que absorbe a luz na rodopsina da retina do ollo humano.
