Ray

 

A ray is a portion of a line. It starts at one point (called starting
point) and goes endlessly in a direction.

Examples of the ray are: Beam of light from a lighthouse and sun rays.

Thus a line segment ar{AB{color{Blue} {color{Blue} }}} extended endlessly in the direction from
A to B, is a ray denoted by vec{AB}

 

The ray vec{AB} has one end (fixed) point called its initial point.

Rays vec{AB} and vec{BA} are two different rays.

Ray vec{BA} is a ray with initial point B and extends endlessly in the
direction from B to A.
