Ultraviolet and infrared are sometimes incorrectly referred to as 'light'. The human eye 'sees' radiation between 400 and 700 nm. Wavelengths above or below this are not visible, and hence, not 'light', unless there is such a thing as 'invisible light'. For that matter, we can refer to X-rays and radio waves as light too.

UV and infrared is correctly called 'radiation'.

Why all this fuss? I got nailed big-time on an exam freshman year about this, a lesson I'll never forget!
