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 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.
