humans will last about 1 second once the sun rays reaches us from the sun blowing up

Not true. Our sun will become a red giant when it runs out of hydrogen and starts "burning" helium. When it does its radius will expand to well beyond the earth's orbit. So the earth will be a burnt-out cinder much before the end of sunlight.
The wavelength of infrared light is too long for humans to see.
We use natural light to see. Amplified light can be used in lasers which can transmit enough energy to cut materials including metal. Optical fibers are increasingly used to transmit digital data, rather than metal conductors.
Ultraviolet light and infrared light are two types of light that humans cannot see. Ultraviolet light has shorter wavelengths than visible light, while infrared light has longer wavelengths. Both types of light are beyond the visible spectrum for humans but can be detected with specialized equipment.
I looked it up in my physics text book and it says that the wavelength is too long to be seen by the human eye.
Humans emit infrared light, which is a type of electromagnetic radiation that is not visible to the human eye.

a very long time.
Oxygen
To humans RED means stop or danger in our brains.

"used cats" cats arent drug!!
light is very help ful to humans because humans need light to see dark and humans need light so they can do their work. that's all i think
it was used in 18816

Light is what humans process faster

YES. Visible light is the leading cause of death of humans on the Earth and is extremely dangerous. THIS IS IMPORTANT. If you see visible light in the wild, DO NOT APPROACH IT. I am the administrator of the Organization for Protection Of Humans from the Dangers of Visible Light (OPOHDOVL). Always remember to watch out for visible light in the daytime. That's when they get you!
