Air Lens Tank

This experiment consists of a tank of water and lens that are made of air instead of glass. The air lens is lowered into the tank and creates a focusing effect that is opposite of glass lenses based on the shape of the lens. Convex glass lenses will converge the light together while convex air lenses will cause the light to diverge.
