There's nothing really special here, it's simply the color of the light that enters our eyes is how we see the traffic light.

Is the only part of electromagnetic spectrum that the human eye detect?
That's the spectral band that scientists have dubbed "visible light".
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.
Is red light visible?
That depends on whether it's still in the visible light range that human eyes can detect. If it's beyond red it will be infrared, a light wave with wavelength/frequency that we cannot detect. The frequency range of red light is between 484 THz to 384 THz. The wavelength of visible red light is between 620 nm to 750 nm.
What are light and dark colors?
Colors like white and yellow are example of light colors while colors like black and brown are example of dark colors.
What came to Garrett Augustus Morgans mind to the Traffic Light?
he invented the traffic light after a see carriage accident.
What are stop light sensor?
Stop light sensors are a loop of wire that is buried in the pavement and controls the traffic light. The sensors are able to detect the traffic that is waiting at the light.
Are traffic light colors related to rastafarianism?
No not at all.
Why cant humans detect infrared light?
They can. While human eyes can not "see" infrared light, humans can detect this light as "heat" on the surface of the skin.
Human eyes can detect this portion of the electromagnetic spectrum?
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.
How do you think the colors of the traffic light were decided upon?
Rastafarians created them ;)
What is visible light and what portion can humans detect?
Visible light waves are the electromagnetic waves which are detected by the human eye. They make up only a small part of the electromagnetic spectrum. So, visible light is any light in which the human eye can detect.
What part of the electromagnetic spectrum can the human eye detect?
VIsual light
The order of colors on a traffic light from top to bottom is?
red, yellow,green
What is the traffic light system?
The Traffic Light Eating Plan follows the Food Guide Pyramid. Each food group can be split into groups based on the colors of the Traffic Light. There are GREEN foods, YELLOW foods, and RED foods.
What colors does a star with nuclear fusion beginning have?
A new star will usually have hydrogen alpha light. This light is red but is difficult for the human eye to detect. If you look up M42, the Great Orion Nebula, most long exposure photographs will show this red light.
The range of electromagnetic waves that human eyes can detect?
visible light spectrum
