we use electromagnetic waves in radios and cell phones
Well, obviously. We wouldn't even SEE without electromagnetic radiation. What's more, we wouldn't even BE ALIVE - since plants get their energy from the electromagnetic radiation emitted by the Sun.

No. Modern-day astronomers do not use only visible electromagnetic radiation to study space. They use additional bands of the electromagnetic spectrum to study space, including radio, microwave, infra-red, ultraviolet, X-ray, and gamma ray. Darn! That's just about everything.
Protection from ultraviolet radiation is what we use sunblock for. UV (ultraviolet) rays have high energy and can damage skin.
Yes, microwave ovens use electromagnetic radiation.
Radio frequency electromagnetic radiation.
Infrared radiation is an electromagnetic wave.

Yes, microwaves produce non-ionizing radiation when in use, which is a type of electromagnetic radiation that heats up food by exciting water molecules.
A radiowave is an example of electromagnetic radiation. What most humans call light - what is produced by the sun or a light bulb - is actually called visible light. Visible light is another form of electromagnetic radiation, but with higher energies. Scientists use the word light as a substitue for the whole generalization of every kind of electromagnetic radiation.
A filament lamp uses infrared radiation, visible light, and a small amount of ultraviolet radiation within the electromagnetic spectrum.
When we use the term "radiation" as regards energy, probably the first thing that comes to mind is electromagnetic energy. Electromagnetic (EM) energy is often called electromagnetic radiation. We know that this could be radio waves, microwave energy, infrared light, light from the visual spectrum, ultraviolet light, X-rays or gamma rays. All of these are forms of electromagnetic radiation, and a link can be found below for more information.Radiant energy.
Electromagnetic radiation with no mass is composed of particles called photons. Photons carry energy and momentum, and they travel at the speed of light. Examples of massless electromagnetic radiation include visible light, radio waves, and X-rays.
