Ray: Definition and Examples
A ray is a line with an endpoint that extends infinitely in one direction. One of the most obvious examples is a sun's ray of light in space. Let's look at how light from the sun originates and travels:
ray of sunlight
The light originates from the sun, and its path extends infinitely (assuming there's nothing to block it). Why do we refer to the light from the sun as sun rays? Why not sun lines? After all, light does travel in a line. However, unlike a ray of light in space, a line has two endpoints. We call this a sun ray because it has only one endpoint (the sun) and extends infinitely in one direction.
If there were no friction, the ball would continue flying through the air after Tommy serves it. The green line indicates the path it would take. This path is another example of a ray. It has an endpoint (in this case, the point where the ball meets the racket), and it would extend infinitely. However, due to friction in the air, the ball will eventually fall to the ground, causing it to travel in an arc.
