Asked by Shirley

We hear people talk of "ultraviolet light" and "infrared light." Why are these terms misleading? Why are we less likely to hear people talk of "radio light" and "X-ray light"?
Answered by drwls
They are misleading because they are oxymorons. Light is visible electromagnetic radiation. Neither ultraviolet nor infrared are visible, but some wavelenghts are close to being visible. Neither XRays nor radio waves are anywhere near being close to visible.
