A thin lens (n = 1.49) immersed in liquid (n = 1.33) has the front surface and the back surface radii of curvature of 10 cm and +20 cm, respectively. Determine the image focal length and the power of the thin lens when it is immersed in the liquid. Determine the image location and magnification produced by the lens for an object located 25 cm in front of the lens immersed in the liquid. Show all the calculations.
