The EM spectrum is a continuous uniform range/domain that has no inherent internal or external boundaries. All delimitation are artificial constructs imposed upon it by man. If you wish to talk about any EM range you agree to definite it for discussion. It does not exists as a natural phenomena.

∙ 11y agoThe distinctions between the "sections" are completely arbitrary ... wherever on
the spectrum we've decided to change the name. Based on how we spread out the
various names, I think you'd have to say that visible light is the smallest section ...
It only extends over roughly one octave of frequency, out of more than 40 octaves
from AM broadcast radio to gamma rays.
Now that I think about it, the definition of the "visible" band is the only one that
actually corresponds to something in nature ... the response of human eyes.

Which of these statements about the EM spectrum is false?
Most of the EM spectrum is visible light.
What is another name often used for spectrum?
The visible light portion of the electromagnetic spectrum.
What is the range of light called?
The visible spectrum is the portion of the electromagnetic spectrum that is visible to (can be detected by) the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light.
How can you use the em spectrum to explore the universe?
The HST uses EM waves to find things through echolocation or firing a beam of EM waves (or sound) at objects and seeing what a planet or star has done to change the light. Ultrasound works this way.
What is the scientific study of rays called?
Astronomers use the EM spectrum, Physicists speculate about it, yet the practical study of it falls to the Mechanical Engineers: your answer = mechanical engineering.
What is the smallest portion of the spectrum?
the smallest wavelengths and the highest energy are gamma rays.
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
The visible portion of the electromagnetic spectrum represent a large portion of the spectrum?
The visible portion of electromagnetic spectrum is called the visible light and is the electromagnetic wave with the wavelength between 380 - 740 nm.
What type of electromagnetic waves are used for radars?
Microwave (portion of EM Spectrum lying between radio wave and infrared wave).
EM radiation often emitted by heat lamps heaters and fires?
That would be the portion of the spectrum called "heat" (far infrared).
What is another word for light waves?
Electromagnetic waves or radiation. "Light," however, generally refers to that portion of the EM spectrum that our eyes can detect.
Which portion of the electromagnetic spectrum is used to identify fluorescent minerals?
The UV portion of the spectrum
Which wavelength must the light contain and the object reflect to appear white?
Refer to the EM spectrum to find exact answer about this question. Usually wavelengths are listed at bottom and frequency on top of the spectrum. Gamma rays have the smallest wavelength.
Is the following true or false the visible portion of the electromagnetic spectrum represents a large portion of the spectrum?
False
How does the em spectrum effect what you see?

What portion of the of the electromagnetic spectrum do radio telescope?
The radio frequency portion of the electromagnetic spectrum uses radio telescopes.
