What do you call a wave that is made up of electromagnetic feilds

In general, no matter what its wavelength is, you can call it

an electromagnetic wave.

If you happen to know its wavelength, then you can be more

specific, and call it a radio wave, an infrared wave, a light wave,

an ultraviolet wave, an X-ray, or a Gamma ray, depending on

what range of wavelengths it's in.

Electromagnetic waves, it just makes sense
