WebLight is the familiar word for what physicists call electromagnetic radiation or electromagnetic waves. Light is a form of energy; it can travel through empty space and is in the form of individual wave packets called photons. The waves in packets of visible light are tiny ripples less than a millionth of a meter long. WebThe Sun. The Sun is the star at the center of our solar system, and is by far the largest member with a thousand times more mass than all the planets, moons, asteroids and comets put together.
