What is made up of electromagnetic radiation?
Electromagnetic radiation is made up of electric and magnetic fields oscillating together in the form of waves. These waves can vary in frequency and wavelength, giving rise to different types of electromagnetic radiation such as radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.
Is all radiation harmful What if any are some good forms of radiation?
-- Radiation at frequencies below 1.7 MHz is good because it helps us hear the news on AM radio. -- Radiation at frequencies between 88 and 108 MHz helps us hear music on FM radio. -- Radiation at frequencies around 1 GHz helps us make cell phone calls. -- Radiation at frequencies around 2.45 GHz helps us heat meatloaf and make popcorn, and it can't hurt us if we're careful with it. -- Radiation with wavelengths between 400 and 800 nanometers is good because it helps us see things so that we don't go around bumping into them. -- Radiation with wavelengths between 300 and 400 nanometers can give our skin a nice healthy glow, and it can't hurt us if we're careful with it. -- Radiation with wavelengths between 100 and 300 nanometers can help the doctor check our bones, and it can't hurt us if we're careful with it. -- Radiation with wavelengths less than maybe 350 nanometers can hurt us if we're not careful with it.
What do all of the different forms of electromagnetic radiation together make up?
All forms of electromagnetic radiation make up the electromagnetic spectrum. This includes visible light, radio waves, microwaves, infrared radiation, ultraviolet radiation, X-rays, and gamma rays. Each type of radiation has a different wavelength and energy level.
Infrared radiation and visible radiation?
Visible radiation (a.k.a. light) is the wavelengths we can see. Infrared radiation lies down below the red end of the spectrum that we can see, hence infra red. But we can make device that both generate and detect infra red radiation. Your TV control works this way.
Is electromagnetic radiation made of photons or the perpendicular oscillation of magnetic and electric fields?
Electromagnetic radiation (EMR) is the oscillation and movement of magnetic and electric fields which are perpendicular to each other. This is the way in which electromagnetic radiation is propagated. Photons are another term for higher energy EMR, and it could also be argued that photons make up some forms of electromagnetic radiation.
All possible kinds of light at all energies frequencies and wavelengths make up the?
Electromagnetic spectrum.
What do the wavelengths of light that our eyes can see make up?
The visible spectrum of the electromagnetic spectrum of radiation
What Is A Family Of Radiant Energy Waves?
A family of radiant energy waves refers to the different types of electromagnetic waves that make up the electromagnetic spectrum. This includes radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. Each type of wave has a specific range of wavelengths and frequencies.
How does sunlight come to earth?
Sunlight travels as electromagnetic radiation through the vacuum of space and reaches Earth by the process of radiation. The Sun emits light in the form of photons which travel at the speed of light and take about 8 minutes to reach Earth.

What electromagnetic waves make your skin feel warm?
Infrared radiation is the electromagnetic wave that makes your skin feel warm. It has longer wavelengths than visible light and can penetrate the skin's surface, causing it to heat up.
How do you make Artificial electromagnetic radiation?
n
What are the names of the wavelengths?
For electromagnetic waves: thermal radiation and radio waves are pretty long. For sound waves: bass sound waves are pretty long, so is quiet. For water waves: the tides

Do the wavelengths that make up the electromagnetic spectrum each have the same amount of energy?
no
Where do electromagnetic waves come from?
A spectrum is a representation of the range of frequencies/wavelengths present in electromagnetic radiation. It may be plotted as the power or intensity on the vertical axis, and the wavelength or frequency on the horizontal axis. When talking about the electromagnetic spectrum it is sometimes presented as a chart or table showing the range of frequencies/wavelengths that are covered by electromagnetic radiation. Thus it represents radiation from radio frequencies through infra red, visible light, ultraviolet light, x-rays and gamma radiation. Where does it come from? The first link below shows the history of "spectrum" which was originally used to refer to the colours of light when split up by a rainbow or prism. It was later used by analogy to refer to "a range of objects". I guess that someone just wanted to make a chart showing how the various radiation types are related.
