Radiant light originates from a single point in space and moves from it's center in 360 degrees. Light travels in straight lines into space, when it does not come into contact with a form it is reabsorbed into the void of space. If light comes into contact with a form it can be absorbed, reflected or refracted. In some cases, depending on the form all three results can occur. Examples of radiant light source the sun, a light bulb or a candle.
