What is Divergent light?

Divergent light is like when you shine a flashlight and it spreads out as it goes farther away.

Imagine you're holding a flashlight and pointing it at the ceiling. Close to your hand, the light is tight and bright, but as it moves away, it gets wider and less bright. That’s divergent light: it starts from one point and then spreads out in all directions, like a fan opening up.

Think of a balloon. When you blow it up, the air inside pushes the rubber outward, everything moves away from the center. Divergent light is just like that balloon: it starts at one point (like your flashlight) and then expands as it travels.

If divergent light is a balloon getting bigger, convergent light is like when you bring the balloon back to a small point, imagine all the air being squeezed into one spot again. Divergent light spreads out; convergent light comes together.
