To work this problem, use the fact that the image formed by the first surface becomes the object for the second surface. The figure below shows a piece of glass with index of refraction n = 1.50 surrounded by air. The ends are hemispheres with radii R1 = 2.00 cm and R2 = 4.00 cm, and the centers of the hemispherical ends are separated by a distance of d = 7.74 cm. A point object is in air, a distance of p = 1.10 cm from the left end of the glass. Locate the image of the object due to refraction at the two spherical surfaces.
