Ultraviolet light has wavelengths measuring between 10nm and 400nm. Visible light, which humans can see, measures from 400 to 700nm.

Now, however, scientists at the University of Queensland in Australia, have developed a new display that also includes violet and ultraviolet, which will allow them to test the visual capabilities of animals that can see into the ultraviolet spectrum. And clownfish (Amphiprion ocellaris) were the first animals to get a front-row seat.
