When the rays of light starting from a point travel in different directions, then the collection of such rays is termed a divergent beam of light. ex a magnifying glass will narrow the light beam. The bulb is at focus of the concave shape. so emerging beam is more of parallel beam than converging.
When the rays of light coming from different directions meet at a point, then the collection of such rays is termed a convergent beam of light.eg. a painted picture drawn on the surface of a flat frosted glass!
