an object is placed in front of a converging lens outside the focal length of 28cm. the lens produces an image that is 4 cm from the lens.

Q: what would happen to the absolute value of the magnification of this object if the lens were placed under water? (Assume the index of refraction of the lens is greater than the index of refraction of water)

a) it would increase

b) it would decrease

c) it would remain the same
