Categorization of Light resources - Point source

This is the easiest model for a light emitter. Currently rays from source obey radically diverging ways from the source position, for instant, sources like LED's or minute bulbs, that are the light sources wherein light rays originate at a point and radially diverge, that type of sources contain dimensions rather smaller as compared to the size of object like as demonstrated in the figure 2, the point source is source a.
