Homework Statement
A thick-walled wine goblet sitting on a table can be considered to be a hollow glass sphere with an outer radius of 4.00 cm and an inner radius of 3.40 cm. The index of refraction of the goblet glass is 1.50.
A) A beam of parallel light rays enters the side of the empty goblet along a horizontal radius from the left. Where, if anywhere, will an image be formed?
B) The goblet is filled with white wine (n=1.37). Where is the image formed?

n1sinθ1=n2sinθ2
1/s+1/s'=1/f
The Attempt at a Solution
I don't know where to start with this problem. I'm confused with the beam of parallel light rays, do they mean just one ray? Or do they mean many rays that cover the entire left side of the sphere? I also considered this to be a thin lens, but there was no object. I'm really just looking for a direction to take this problem. Thanks
