Visible rays of sunlight in the sky are called crepuscular rays. They are caused by light shining through holes in clouds being scattered by dust or moisture in the air.

Diffusion. You're probably speaking of the thermal disturbance of our atmosphere, I.E., the sun's light (heat) creates molecular movement of a gas (our air.) You're not actually seeing sun rays in this fashion, but only the sun's heat disturbing our air. To actually see a sun ray, you have to look directly at the sun, the source. (Which, of course, isn't a good idea.)

On the airless moon, there is a very distinct line of demarcation, since there is no diffusion of the sun's light. This can be compared to the lines emanating from the exact center of a circle -- called radii. The number of radii emanating from the center of a circle are incalcuable, expressed as 1/infinity. Same for the rays of the sun. Crepuscular rays usually refer to those of the low sun, most affected by our atmosphere, ie dusk, and for some specific or unique purposes, dawn.
