Does the focal length get longer or shorter

Reference no: EM13694751

Question: A converging glass lens (n = 1.40) is immersed in water. Does the focal length get longer or shorter and by what factor? Explain why.

I want you to explain the physics in this problem. Hint: In the lens maker formula, the term n - 1 is actually the difference between the index of refraction of the lens and the surrounding air.
