Those are called electromagnetic waves.
the energy that makes the electromagnetic spectrum is electromagnetic radiation
Doppler radar wouldn't be possible if the speed of light were infinite. Also it wouldn't be possible if the electromagnetic waves didn't reflect on objects. Also it helps a lot if those electromagnetic waves have a particular frequency as opposed to a wide spectrum. --Some person named Adrian who did the research
Visible light waves are the electromagnetic waves which are detected by the human eye. They make up only a small part of the electromagnetic spectrum. So, visible light is any light in which the human eye can detect.
The Electromagnetic Spectrum.
Why electromagnetic waves of course. These are waves that require no material medium for their propagation, but instead propagate by the cyclic exchange of energy between their electrical and magnetic fields (which for a given wave are always polarized perpendicular to each other, as shown in the image above).The spectrum of electromagnetic waves is continuous with no gaps and spans a potential range of wavelengths from as small as roughly the diameter of protons and neutrons to almost as large as the known universe. Different bands within this spectrum interact with matter in different ways, have been given different names by humans, and some of these bands are used by humans for a variety of different purposes (e.g. communication, RADAR, cooking, heating, vision, medical).
Spectrum
Electormagnetic (EM) waves are all the waves and subsequent wavelengths that make up the Electromagnetic Spectrum. This includes but is not limited to: Radio Waves Infered Waves Visible Light Micro Waves X- Rays If you want a complete list look up the Electromagnetic Spectrum.

"Color" is a property for part of the electromagnetic spectrum. It doesn't make sense for other types of radiation, including gravitational waves.
