The eyes of all seeing animals are restricted to a narrow range of the electromagnetic spectrum with wavelengths from about 400 to 700 nm (nanometers). Within this range, not all animals can distinguish between different colors; some see in shades of grey.
A healthy human eye, which does distinguish between different colors, normally detects wavelengths from 390 nm (violet) to 750 nm (red). Some animals can detect wavelengths slightly into the ultraviolet region of the spectrum, i.e. wavelengths shorter than 390 nm, that humans cannot detect.
Colors that are visible to humans run from violet through blue, cyan, green, yellow, orange, and finally red. Brown is a mix of red, yellow, and blue. White is a mix of all the colors at once. Black is not a color, but the lack of color because a black surface absorbs light without reflecting much of it back.

What form of radiation can your eyes detect?
Our eyes can detect radiation of wavelength ranging from 4000 Angstrom to 8000 Angstrom.
Why light rays are considered as electromagnetic waves?
Mainly because that's what they are. Exactly the same physical phenomenon as radio, microwave, heat radiation, ultraviolet, X-rays, and gamma rays, but with wavelengths in the narrow range that your eyes can detect.
Why did human eyes evolve to detect visible light?
Because the people whose eyes could not detect visible light didn't surviveto have children. They were completely outclassed, outhunted, and outfoughtby the people whose eyes could detect it.
What wavelengths can astronomers detect from earth?
Only those which aren't absorbed too much by the atmosphere. Those are visible light, and radio waves.
What are the detectors of visible light waves?
The eye and photosensitive paper both detect visible light.
Why can wavelengths of light be seen by humans?
Our eyes can detect them.
Why does a rainbow show colors from reds to violet?
There's a broad band of wavelengths of light coming from a rainbow. They range from wavelengths that are too short for your eyes to detect, all the way to wavelengths that are too long for your eyes to detect. Within that band of wavelengths is the total band that your eyes can detect, and you see them as a spread out display of all the colors that your eyes and brain can work together to perceive.
What can ocelli detect?
Tiny eyes (also called ocelli) that can detect light and dark are located on top of the spiders cephalothorax. They also can detect different wavelengths and intensities of light.
Which wave can your eye detect?
If you mean, "which wavelengths of light can the human eye detect," the human eye can see wavelengths from about 390 to 700 nanometers.
Why are there diiferent telescopes in space?
To detect different wavelengths of the electromagnetic spectrum.
What is the purpose of compound eyes for grasshoppers?
Compound eyes detect motion, and simple eyes detect light. or The compound eyes are used to "see". The simple eyes are used to detect light intensity.
Why the wave length 700nm is red for human eye?
Our eyes are able to detect light with a wavelength between about 390nm to 750nm. Different colors are seen when the eyes detect different wavelengths. "Red" is just the name given to the color seen at around 700nm. Food for thought, does everyone see the same color red? (My guess is probably not)!
What form of radiation can your eyes detect?
Our eyes can detect radiation of wavelength ranging from 4000 Angstrom to 8000 Angstrom.
Why do you call the visible light part of the EMS visible light?
Because it's comprised of the band of wavelengths that the human eye can detect, that is, wavelengths that are 'visible' to human beings.
How do humans see colors in wavelengths?
Most humans eyes are sensitive to wavelengths between about 400 nanometers and 700 nanometers
Why light rays are considered as electromagnetic waves?
Mainly because that's what they are. Exactly the same physical phenomenon as radio, microwave, heat radiation, ultraviolet, X-rays, and gamma rays, but with wavelengths in the narrow range that your eyes can detect.
What radiation energy can your eyes detect?
No
