Sunlight is the visible part of the electromagnetic radiation that extends from the Sun as it burns through nuclear fusion. The light which appears white contains energy beyond what the eye is able to see, and is the primary energy source for life on earth. Beyond the visible spectrum, sunlight also contains Infrared (IR) and Ultra-Violet (UV) light.
