Answer 2

Hello there...
I'm Rajdeep...

A concave lens is thinner at the middle and thicker at the periphery, but a convex lens is thicker at the middle and thinner at the periphery.
So if you immerse a bubble in water, a bubble I'd thicker at the middle than its thickness at its poles, so it acts as a convex lens.
