What is Light?
Light is a form of energy that travels in waves. It is made up of different colors, including red, orange, yellow, green, blue, indigo, and violet. Light travels in a straight line until it hits an object. When it does, it is either absorbed, reflected, or refracted. Light travels very quickly -- at 186,000 miles per second! That's why it only takes about 8 minutes for light from the sun to reach the Earth.
Light is the only form of energy visible to the human eye. Light travels faster than sound. The speed of light is constant in a vacuum, at 299,792,458 meters per second.
