Every part of the electro-magnetic spectrum could be used for communications however the most exploited are long radio waves, short radio wave, and micro-waves.
Telescopes are used to observe and magnify images in outer space. The electromagnetic spectrum consists of many wavelengths, which constitute visible light, infrared, microwave, and X-ray radiation. Telescopes can be manufactured to view these certain types of radiation.
Electromagnetic spectrum is the range of wavellengths of different radiations reflected or emitted by objects with temperature above 0 k. Remote sensing technology make use of such radiations of certain wavelength in EM spectrum to distinguish different objects as different object radiates differently.
Primarily Yellow but really it uses most of the visible spectrum, just some parts more than others. Green plants actually have five type of pigments that serve in photosynthesis. When the leave of the deciduous trees turn in autumn you can see the colours of many of these as they are selectively withdrawn.
All the types on the electromagnetic spectrum (e.g. infrared, ultraviolet, visible, radio, etc.)
Many particle physicists, radiation specialists, opticians and ophthalmologists have gotten togetherand named that part of the spectrum the "visible light" band.
The total of all electromagnetic waves is called the electromagnetic spectrum. The electromagnetic spectrum includes radio waves, microwaves, infrared radiation, visible light waves, ultraviolet radiation, x-rays, and gamma rays. Only visible light waves, which humans see as the band of colors from red to violet, are the portion of the spectrum visible to the human eye, although many other life forms are sensitive to infrared and possibly to other segments the spectrum.
The electromagnetic spectrum is a continuum so that the boundaries between its parts are arbitrary.From waves with the largest wavelengths (lowest frequencies and energies), they are:sub-radio frequencyradio wavesmicro-wavesterahertz radiationinfra redvisible lightultra violetx-raysgamma raysThe arbitrariness is seen in the boundary between visible and ultraviolet, for example. Many insects can see near ultraviolet.
Visible light, which lets humans and other animals see, is part of the electromagnetic spectrum. RF (radio frequency) waves are part of the electromagnetic spectrum. RF transmissions carry radio and television broadcasts. They have the lowest frequency. Microwaves are part of the electromagnetic spectrum. X-Rays are part of the electromagnetic spectrum and have the highest frequency..
Because many stars emit energy unevenly over the electromagnetic spectrum. Thus extremely energetic objects would be brighter in X-rays (more energetic than visual light) and some brown dwarfs would be easier to perceive in the infrared. Combining images from across the spectrum avoids the three blind men and the elephant issue.
In a vacuum, electromagnetic waves from all parts of the electromagnetic spectrum can indeed propagate. Unlike mechanical waves, such as sound waves, which require a medium (like air, water, or solids) to travel through, electromagnetic waves do not require a medium and can travel through the vacuum of space. The electromagnetic spectrum encompasses a wide range of frequencies, including radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. Each type of electromagnetic wave has its own characteristic frequency, wavelength, and energy. In a vacuum, electromagnetic waves travel at the speed of light, which is approximately 299,792,458 meters per second (or about 186,282 miles per second) in a vacuum. This speed is constant for all electromagnetic waves in a vacuum, regardless of their frequency or wavelength. Electromagnetic waves can travel through space, transmitting energy and information over vast distances. They play a crucial role in various natural phenomena, such as the transmission of sunlight from the Sun to the Earth, the propagation of radio signals through the atmosphere, and the emission of X-rays and gamma rays from distant astronomical objects. In summary, electromagnetic waves from all parts of the spectrum can travel through a vacuum, allowing them to propagate freely through space without the need for a medium. This property of electromagnetic waves enables them to play essential roles in communication, astronomy, medicine, and many other fields of science and technology.
You could certainly call it that if you like, but most people wouldn't know what you mean. Many of them would understand you better if you called it the "electromagnetic spectrum", (while the rest would still be lost).
Most stars and many other objects in space emit radio and microwave radiation. Even the big bag emitted electromagnetic radiation.

The part between 400 and 700 nanometers called the visible spectrum. Red to Violet.

Yes. What you need to look at is the electromagnetic spectrum. There are many great graphical illustrations of this on the web.
