Homework Statement


A small light bulb is placed 10.0 cm from the center of a plastic sphere of radius 1.0 cm
and refractive index 1.40. Where is the image of the bulb?

Homework Equations


1) Thin lens equation
2) Thick lens equation


The Attempt at a Solution


I realize that I'm going to have to treat this object as a lens, but I'm not totally sure about whether to use the thin lens formula or not. Would I treat this object as a "thick" lens and use its diameter as its thickness? Or is the spherical nature of the object going to require another equation? Thanks in advance.

Do you have a definition for a thin lens? If not, try Wikipedia.
