All types of electromagnetic radiation are invisible - except the part called visible light.
Ultra-violet and x-rays carry more energy per photon than visible waves.
Infrared waves have a lower frequency than visible light.
One of them is Radio.
Those are called x-rays.
Radio
Heat
infrared
"Absorbed"
No, not in general. It is rather the other way around. Infrared radiation is electromagnetic radiation, and electromagnetic radiation spans multiple types of radiation, from microwaves, light, infrared, ultraviolet, radio, and more. So electromagnetic radiation could be infrared, but that is just one type of electromagnetic radiation
Yes, that is correct. The radiation generated by the Big Bang is called the cosmic microwave background (CMB). As the universe expanded and cooled over billions of years, the high-energy radiation transformed into lower-energy microwaves. Today, the CMB is detected as a faint glow of microwaves that permeates all of space and provides crucial evidence for the Big Bang theory.
Microwaves and radio waves.
The closest is infrared radiation.
Radio.
Though not all radiation is electromagnetic, a lot of it is. Sound, which is mechanical energy, can radiate. It is a type of radiated energy. There are others. But radio waves, microwaves, light, X-rays and gamma rays are all forms of electromagnetic energy. The only difference is the frequency or energy of the radiation (and we lined them up for you from lower frequency to higher frequency). The universe is awash is electromagnetic energy. It's all around us. Use the links below to learn more.
Microwaves are a frequency of electromagnetic radiation. It has a higher frequency than radio waves, but has a lower frequency than infrared light.
Yes, since the oven heats food by irradiating it with microwaves. Microwaves are an example of electromagnetic radiation, having a frequency lower than that of visible light.

Infrared (or radiant heat).
Whenever the electron falls from an excited state to a lower level, energy is released in the form of electromagnetic radiation. The Electromagnetic radiation can be light of different wavelengths and therefore different colors
You have gamma rays, x-rays, ultraviolet rays, light rays, infra red rays, microwaves and radio waves in increasing order of wave length and and decreasing order of frequencies. Out of which radio waves have lowest energy. Longer the wave length, lower is the energy.
Heat, infra-red, microwaves and radiowaves
Radio - in all its variations.
Yes, that is correct. The radiation generated by the Big Bang is called the cosmic microwave background (CMB). As the universe expanded and cooled over billions of years, the high-energy radiation transformed into lower-energy microwaves. Today, the CMB is detected as a faint glow of microwaves that permeates all of space and provides crucial evidence for the Big Bang theory.
