Good question-- See the link. Roughly the visible region is 300 nm to 650. so that's 350 nm total. The electromagnetic spectrum goes from 10 Megameters to 1 picometer. So the percentage of the spectrum occupied by visible light is tiny, just 3.5 X 10-9 divided by 10^19 So that's 3.5x10-26 %. So many zeros....! Yikes. Gamma rays (picometers) (10-12)
Hard X-rays
Soft X-Rays

So really the answer is 0%. If you meant to ask what percentage of the electromagnetic energy from the sun is visible (for instance) then the answer is nonzero, but I don't know what it is. If you meant to ask a question of the kind that has been answered above (what percentage of the spectrum from 10 megameters to 1 picometer is visible) then the question is not well defined: the answer depends not just on the bounds but on what scale you use. I think the answer above is mistaken. If you go by wavelength, my answer (to that question) would be: 3.5x10-7 divided by 107, which is 3.5x10-14 or 3.5x10-12%. If you use frequency instead of wavelength: The bounds on wavelength given above correspond to 30 Hz to 3x1020Hz, with visible light between 4.6x1014Hz and 1015Hz. Then, the answer would be 5.4x1014 divided by 3x1020, which is 1.8x10-6, or 0.00018%. If you want to use a logarithmic scale, which is more sensible in some ways, then the answer is much higher. I don't know exactly because I don't have a calculator with logarithms here, but it's around 1.5%.

Where is visible light found in the electromagnetic spectrum?

Electromagnetism is manifest along a continuum between slower radio waves and faster energy gamma waves. Visible light can be found in the range between infrared light (slower than waves of visible light) and ultraviolet light (faster than waves of visible light).

What spectrum is visible light part of?

Visible light is part of what is called the electromagnetic spectrum . Light is electromagnetic energy, and so are radio waves, microwaves, X-rays and gamma rays.

How much of the entire electromagnetic spectrum do humans see as visible light?

The EM spectrum ranges from very long radio waves at around 1000m or longer, to gamma rays at around 0.01 nanometers (nm). The visible part of the spectrum (for human eyes) ranges from 700 nm (red) to 400 nm (violet). One nanometer = 10 -9 meter. You may sometimes find reference to Angstroms, wh ( Full Answer )

Is most of the electromagnetic spectrum composed of visible light?

No only a very small portion of the electromagnetic spectrum is composed of visible light, roughly the range of 400 terahertz to 800 tera hertz is visible light. The spectrum is many thousands of terahertz larger than the .4 terahertz containing visible light.

How is visible light related to the electromagnetic spectrum?

Visible light is a subset of the electromagnetic spectrum. Starting at the longest wavelengths (lowest frequencies), the electromagnetic spectum includes: . Radio waves . Microwaves . Infra-red . Visible light . Ultraviolet . X-rays . Gamma rays . Refer to the related link below for add ( Full Answer )

What is the visible light range of the electromagnetic spectrum?

Answer ALL THE COLORS YOU CAN SEE: Red Orange Yellow Green Blue Indigo Violet The electromagnetic spectrum is all the waves, from radio waves to cosmic rays, with visible light waves only occupying an infinitesimally small section of the complete spectrum. Answer It is the range at which the hu ( Full Answer )

What fraction of the electromagnetic spectrum is visible light?

Less than 5% of the electromagnetic spectrum is visible light, wavelength of approx 400 nanometers (violet) to 700 nanometers (red). The entire spectrum goes from gamma radiation (wavelength 1 trillionth of a nanometer) to radio waves (wavelength measured in kilometers)

How is the visible spectrum related to the electromagnetic spectrum?

The visible light spectrum is right in the middle of the electromagnetic spectrum. The spectrum ranges from low frequency, low energy radio waves to high frequency, high energy gamma waves. We as limited as we are biologically cannot physically sense anything outside the visible spectrum without the ( Full Answer )

Which color of the visible light portion of the electromagnetic spectrum has the highest frequency and the most energy?

Violet, with a wavelenght between 380 and 450 nm, which is near the end of the visible light, next to the ultraviolet region. Be careful because talk about "colors" is quite dangerous. Firstly, different cultures has different names for the same color. In addition to this, due to the fact that th ( Full Answer )

How much electromagnetic spectrum is visible?

The part of the electromagentic spectrum from the bottom of the AMradio dial ... 550 KHz ... to the lowest-frequency gamma rays ... 10 19 Hz ...covers roughly 44 octaves. Out of that, roughly one octave isvisible to the human eye. (maybe 380 - 750 nanometers)

How does the size of visible light compare to the rest of the electromagnetic spectrum?

That's hard to discuss, because the electromagnetic spectrum has no ends. If you name a frequency, then no matter how low it is, I can name a lower one, and no matter how high it is, I can name a higher one. So, it's easy to describe the size of the visible portion, but it's hard to describe t ( Full Answer )

Who discovered the visible spectrum of light?

Isaac Newton discovered the visible spectrum of light while fooling around with a prism (from which is derived the basic principle of a rainbow.) He later wrote about his findings in his well-known book, Optiks. Isaac Newton was also a master of atsronomy, calculus, and physics. It was also he who ( Full Answer )

What is the visible spectrum of white lights?

The visible spectrum is red , orange , yellow , green , blue , indigo , and violet . You can remember this by remembering ROY G. BIV as a man's name.

How does the width of the visible spectrum compare to the entire electromagnetic spectrum?

It is very short compared to the whole length of the EM spectrum. ======= Another contributor rushed in where the first feared to tread: First of all ... there's no such thing as the "entire electromagnetic spectrum". If you name a frequency, then no matter how low it is, I can always nam ( Full Answer )

What percentage of the solar spectrum is visible light and how does it change during the day?

Sunsets have always captured the imagination with their brilliant Calvin more so when people discover that sunsets vary depending on location, or when they discover an unusual or especially colorful sunset. Sunsets in the desert tend to be very orange, whereas the sunsets in urban areas tend to be m ( Full Answer )

What is the relative size of the visible light spectrum as compared to the entire electromagnetic spectrum?

Is visible light part of a larger electromagnetic spectrum?

Yes it is. A very small part, in fact. The phenomena you know as radio, microwave, heat, infrared, ultraviolet, X-rays, and gamma rays are all exactly the same physical entity as visible light, differing only in their wavelengths (or frequencies).

How does the visible light spectrum compare with the size of the electromagnetic spectrum?

It's hard to come up with a definite number, because the totalelectromagnetic spectrum has no definite edges.

However, I havehand ( Full Answer )

What color has a lower frequency of visible light in the electromagnetic spectrum?

The color spectrum in order of increasing frequency (that also means decreasing band width) is red, orange, yellow, green, blue, violet. So red is the lowest visible frequency.
