Are infrared, visible, and ultraviolet all types of light, while radio waves and X-rays are not?

Infrared, visible, and ultraviolet light are all indeed forms of electromagnetic radiation, which is commonly referred to as "light." This encompasses a broad spectrum of wavelengths, including those that are visible to the human eye as well as those that exist outside the visible range, like infrared (longer wavelengths) and ultraviolet (shorter wavelengths).

Radio waves and X-rays are also types of electromagnetic radiation. Radio waves have much longer wavelengths and are used in broadcasting and communication, while X-rays have much shorter wavelengths and are utilized in medical imaging and other applications. Thus, the classification of light is not limited to just infrared, visible, and ultraviolet; it includes radio waves, microwaves, X-rays, and gamma rays as well.

The assertion that radio waves and X-rays are not types of light is incorrect because they are part of the same electromagnetic spectrum. Therefore, the statement in the question is false.
