3) (20 pts.) Compute the focal length of a biconcave thin lens immersed in water. The lens is made of flint glass, with index of refraction 1.66. The radii of the surfaces of the lens are 10 cm for the left surface and 20 cm for the right surface (both given in magnitude). The index of water is 1.33.
