The part with wavelengths between roughly 380 and 750 nanometers,
and almost universally referred to, coincidentally, as "visible light".

What is energy from the sun known as?
solar The sun releases electromagnetic energy in the entire EM spectrum from radio waves up to Gamma radiation
Does the sun give off gamma rays?
Yes - as with all other wavelengths on the em spectrum - however, not to a high intensity. You'd be surprised the moon is actually brighter than the sun when viewed in 'gamma ray vision'.
Stars produce their energy by what process?
Solar Fusion, the conversion at high temperature and pressure of hydrogen and other gases into radiant heat and gamma radiation.
What is the difference between Infrared and visible satellite images?
Electromagnetic (EM) radiation is the word we use for any sort of energy wave that propagates through space. We can measure the frequency of the wave, or the wavelength. The speed of light is 186,000 miles per second, which is about 300,000,000 meters per second. We can use this to convert frequency to wavelength; the frequency (in Hertz) times the wavelength (in meters) equals the speed of light. The EM spectrum includes radio, microwaves, heat, light, X-rays and gamma rays; it is all electromagnetic radiation, and the only difference is the frequency (or wavelength). So heat rays are part of the EM spectrum that is just below the red color of light, so "infra-" (below) red; infrared. Infrared (IR) is light that is a frequency a little below what our eyes can see, just as ultraviolet (UV) rays are just light that's a little higher in frequency than our eyes see. We see when light is reflected back to our eyes. When light hits vegetation, it reflects best in the IR range, so satellite photos in the IR range can see tiny changes in the way we see plants.
What do scientists think about the great pyramids?
Aliens built em
Is visible light a major part of the EM spectrum?
It is certainly a very important part, but it is not a major part; 'visible light' makes up only a tiny part of the EM spectrum.
What is the highest frequency part of EM spectrum?
That's the gamma radiation.
Which of these statements about the EM spectrum is false?
Most of the EM spectrum is visible light.
Where is wave located on the em spectrum?
all of the em spectrum is measured i waves
What part of the EM spectrum do you use to see stuff?
That part is called "visible light", or just "light".
Why isn't sound a part of the em spectrum?
Sound is a mechanical wave, not an electromagnetic wave.
What are the types of waves in the electromagnetic spectrum?
All electromagnetic (EM) waves are in the EM spectrum. This is from "ELF" (3-30hz) through visible light (300Thz+), out past gamma rays. Any wave above DC that broadcasts into space is part of the EM spectrum.
What two properties of a em wave change as you move from one part of the em spectrum to another?
frequency and heat. (Color can change, too)
Why is it true to say that all EM radiation is light even though we can see only a small slice of the spectrum as visible light?
Visible light is a very small part of the EM spectrum and it is intellectual laziness to refer to all EM radiation as light.
How is the electromagnetic spectrum useful?
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..
Where is the cosmic rays radiation located on the electromagnetic spectrum in relation to other kinds of radiation?
Cosmic rays are not part of the EM spectrum -- they are high energy charged particles.
How does the troposphere filter out part of the EM spectrum?
The troposhpere is thick (relatively speaking) with gases and so more high energy EM waves are absorbed before they can reach the ground.
