Expert Answer:

An air bubble inside a transparent liquid behaves as a convex lens made of air .Its focal length is given by 

Syntax error from line 1 column 49 to line 1 column 73. Unexpected '<mstyle '.

The refractive index of the air bubble is 1 and of water is 1.33. Since the refractive index of the material is less than the medium it will behave as diverging lens.
