It's the electromagnetic spectrum.

Yes, they are not.
Both infrared and ultraviolet are kinds of electromagnetic radiation, as is the visible light.
Ultraviolet is higher frequency, then visible light, then infrared.
infrared light
Ultraviolet and Infrared.
Ultraviolet and the infrared.
Infrared, Visible, & Ultraviolet
The difference is their wavelengths.
Visible light and ultraviolet rays are forms of electromagnetic radiation (EM). So are infrared, microwave and others.
All of them are electromagnetic waves.
Just beyond the limits of visible light are ultraviolet (UV) and infrared (IR) light.
Right between infrared and ultraviolet. It has higher frequencies than infrared; lower frequencies than ultraviolet.
