Colors We Can't SeeThere are many wavelengths in the electromagnetic spectrum the human eye cannot detect. Energy with wavelengths too short for humans to seeEnergy with wavelengths too short to see is "bluer than blue". Light with such short wavelengths is called "Ultraviolet" light. How do we know this light exists? One way is that this kind of light causes sunburns. Our skin is sensitive to this kind of light. If we stay out in this light without sunblock protection, our skin absorbs this energy. After the energy is absorbed, it can make our skin change color ("tan") or it can break down the cells and cause other damage. Energy with wavelengths too long for humans to seeEnergy whose wavelength is too long to see is "redder than red". Light with such long wavelengths is called "Infrared" light. The term "Infra-" means "lower than". How do we know this kind of light exists? One way is that we can feel energy with these wavelengths such as when we sit in front of a campfire or when we get close to a stove burner. Scientists like Samuel Pierpont Langley passed light through a prism and discovered that the infrared light the scientists could not see beyond red could make other things hot. Very long wavelengths of infrared light radiate heat to outer space. This radiation is important to the Earth's energy budget. If this energy did not escape to space, the solar energy that the Earth absorbs would continue to heat the Earth. Which wavelength is the longest?Gamma rays have the longest wavelength.
What color in the visible spectrum has the longest wavelength Brainly?Red waves have the longest wavelengths.
