A lens of thickness t = 21 cm has convex radii of curvature of magnitude R1 = 24.5 cm and R2 = 42 cm. The index of refraction of the lens is n = 1.58. An object “O” is placed 94.5 cm to the left of the lens. Where is I2, the image due to the second surface, relative to the first surface? Answer in units of cm. I have calculated I1 as 120.689376.
