WebThe concept of a ray is very useful. It is a line drawn in space that corresponds to the direction of the flow of radiant energy. Rays are a geometric idealization; they have no width. As such, a ray is a mathematical device rather than a physical entity. In practice, we can produce very narrow beams or pencils (as, for example, a laser beam ...
