Homework Help: Object magnification after Convex surface

  1. Dec 9, 2005 #1
    I have an object that is surrounded by air and sits a distance U=30 from a convex surface. The convex surface has a radius of R=5. The index of refraction of the refracting media is n=1.33. How do I determine the magnification of the object?

    I think, if you find out where the object falls after refraction using the lens maker forumla([itex]R_2 = \infty [/itex]), you can calculate the magnification using some simple geometry

    It is not a thin lense. It is a convex interface between two materials.

    My mistake then.
    The general equation of refraction at a spherical surface will be

    [tex] \frac{\mu_2}{v} - \frac{\mu_1}{u}=\frac{\mu_2 - \mu_1}{R} [/itex]
