Question

what type of lens is an air bubble inside the water?​

Answer 1

Inside water, the air bubble behaves like a Concave lens. The concave lenses are known as diverging lenses as the rays diverge after falling on the concave lens. The air bubble is a sphere with a convex surface and when light reaches it, the light is reflected within the water as in a concave lens.
