302 CHAPTER 23 23.63 . (a) The lens maker’s equation for a lens made of material with refractive index and immersed in a medium having refractive index is 1 1.55 n = 2 n 12 21 2 1.55 11 1 1 1 nn RR n  =− −=   2 1 fn Thus, when the lens is in air, we have 1 1.55 1.00 1 1 1.00 air fR R (1) and when it is immersed in water, 1 1.55 1.33 1 1.33 water = 1 R (2) Dividing Equation (1) by Equation (2) gives 1.33 1.55 1.00 0.55 1.33 1.00 1.55 1.33 0.22 water air f f   ==     79.0 cm air f = () If , the focal length when immersed in water is
