'Ultra'violet light is so-named because the spectrum consists of electromagnetic waves with frequencies higher than those that humans identify as the color violet. These frequencies are invisible to most humans except those with Aphakia. Strangely enough, ‘near UV’ is visible to a number of insects and birds.
