Why can't I see anyone in the chatrooms?

Has anyone been able to see colors most humans cant?

• Has anyone been able to see colors most humans can't? I think I read something once about how someone invented some sort of invention that uses the electromagnetic spectrum because they had a damaged eye and could see colors other people couldnt. Is this true? I dont remember if it was the invention of the XRAY, the Television, or even something else. Can anyone help?

• Answer:

  Yes, you are correct to remember the fact. I have two very interesting article with web-site information about electromagnetic spectrum. Read and refresh your knowledge what you might have read before. After reading the information please let me know what is opinion about it. Was it helpful? --------------------------------------… http://library.thinkquest.org/28160/english/speedwave/electro.html The entire electromagnetic spectrum is made up of ultraviolet, visible light, and infrared. The human eye can only see the light sector of the spectrum. The ultraviolet and infrared are wave energy that can not be seen by our eyes. William Herschel began down the road to discovering the electromagnetic spectrum in 1799. He wanted to find out how light and heat were connected. He used a prism to break up white light and used a thermometer to measure the temperature of each of the different colors. Each color, he found, did not have the same temperature. Red had the highest reading of all of the colors, while violet gave the lowest. However, past the red that we are able to see, Herschel found something that was even hotter than red itself. This end of the electromagnetic spectrum he called infrared. Infrared can be felt, but it can not be seen by the naked eye. The wavelengths of the visible spectrum are all medium in length. The wavelengths of infrared light are very slow. Everything emits infrared light. Even things found in your freezer emit it. Infrared can be found in anything above absolute zero. The amount of infrared light that an object emits depends on its temperature. A human gives off much more infrared light than an ice cube would. No matter what time of day it is, the same amount of infrared light is given off. Because of this, movement can be detected in the dark with infrared detectors. Some animals, like snakes of the pit viper family, are able to pick up on infrared waves to detect their prey.
