Light is a primary tool for perceiving the world and interacting with it for many organisms. Light from the Sun warms the Earth, drives global weather patterns, and initiates the life-sustaining process of photosynthesis; about 10 22 joules of solar radiant energy reach Earth each day.

Light, visible light, or visible radiation is electromagnetic radiation that can be perceived by the human eye. [1][2] Visible light spans the visible spectrum and is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz.
Light: Science and Applications is an open access journal that publishes the highest quality articles in basic and applied optics and photonics.
And our entire understanding of the interaction of light and matter requires light to act like particles known as photons. Perhaps the easiest way to think of light is as a stream of particles, but quantum particles, which are unlike ones that we can see.
