Morphology
The meaning is directly compositional: 'ultraviolet' names a region beyond violet in the spectrum and 'light' names electromagnetic radiation, so the phrase straightforwardly denotes that portion of light. This is a common scientific compound with equivalent constructions in many languages, making it predictable for a learner who knows the constituents.
Etymology
Ultraviolet light comes from its parts ultra (meaning 'beyond') and violet (the deep purple color at the end of the rainbow). So the name shows it is light just beyond violet that our eyes cannot see but that can cause sunburn and kill germs.
