how light produce?? and why we can see it?
why we can see light?? we can see normal visible light wave but why infared wave ??

I don't believe that at all.Pengwuino said:SOOOOOOOOOOOME people can see infrared as well... but the rest are pretty much out of our visible spectrum.
The tiger pistol shrimp and pit viper come to mind.Many animals can see infrared however!

Let's just bring some reality to this. There is no hard and fast boundary between red and infrared - it's a continuum. If you had a colour calibration card that spanned the spectrum, including IR, the farther reds would appear increasingly black.Pengwuino said:Then you smell!
Actually there are a very very very very incredibly rare number where people do have that capability to a small extent.
What? Just when we were having so much fun calling each other names?Let's just bring some reality to this.
Light is produced when atoms or molecules release energy in the form of photons. This can happen through various processes such as thermal radiation, electrical discharge, or chemical reactions.
We are able to see light because our eyes contain specialized cells called photoreceptors that are sensitive to certain wavelengths of light. These photoreceptors convert light into electrical signals that are sent to the brain, allowing us to perceive and interpret the light as different colors and shapes.
The speed of light is approximately 299,792,458 meters per second in a vacuum. This is the fastest speed at which energy, information, or matter can travel in the universe.
Light travels in a straight line and at a constant speed until it encounters an obstacle or is absorbed by a material. It can travel through a vacuum, such as in outer space, or through a medium, such as air or water.
The color of an object depends on which wavelengths of light it reflects or absorbs. For example, a red object appears red because it reflects red wavelengths and absorbs all other colors. A white object reflects all wavelengths, while a black object absorbs all wavelengths, giving it the appearance of being black.
