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”?

I think what this is trying to get you to see is, we call the part of the EM spectrum we can see, light. If you can't see it, it is not light, like x-rays. You can't see infrared or ultraviolet either. They just happen to be the part of the spectrum that is nearest to light.

if you define light as what you can see,
then infrared is no light, you can't see it. :)

The terms are not misleading because ultraviolet and infrared are types of electromagnetic radiation, or light. People may believe the terms are misleading because when we think of light, most people only think of the narrow visible spectrum (VIBGYOR). 

$\bigstar$ It's all in people's minds. People also tend to think of radio waves as signals, and X-rays as just pictures. But in reality, these are also types of light, it's just that they are outside the range we can normally see.

Webster says Light is that which makes vision possible or That part of the EM spectrum that is visible to the human eye.  UV light or IR light are misnomers.   Light is EM radiation but not all EM radiation is  light.
