Difference between convergent and a divergent beam of light.
| Convergent beam | Divergent beam |
| 1. Rays of light converge to a point as the beam progresses | Rays of light diverge from each other as the beam progresses |
| 2. The rays concentrate at a point | The rays emerging from a point source |
| 3. A parallel beam of light converges on passing through a convex lens | A parallel beam of light diverges on passing through a concave lens |
