Does observed gravitational lensing correspond to a converging or diverging lens? Explain briefly.

When a massive volume of matter, such as a cluster of galaxies, forms a gravitational field that bends and magnifies light from distant galaxies that are behind it but in the same line of sight, this is known as a gravitational lens. It's as if you're staring through a huge magnifying glass.

A converging lens relates to gravitational lensing. Because celestial objects bend parallel rays towards their centre in the same way that converging lenses focus parallel rays to a point, this is the case.

We can see stars that would otherwise be entirely obscured by other celestial objects thanks to gravitational lensing. We could see both converging and diverging lensing if a hypothetical negative gravitational charge (mass) was discovered!
