Light is a form of energy that allows us to see. Darkness is the absence of light. The main sources of light on Earth are the sun, stars, flashlights, light bulbs, fires, and candles. Objects can be seen when light reflects off of their surfaces and enters the eyes. Shadows form in areas without light and take on the shape of the object blocking the light. Shadow length varies throughout the day, being longest in the morning and shortest at noon. A prism can separate white light into the colors of the visible spectrum. Dark colors absorb sunlight more than light colors, so dark colors keep a person warmer in winter.
