Homework Statement
Would it be possible for someone to breakdown the different type of lenses and mirrors and their properties like distance of object, distance of image, magnification, type of image (real/virtual, upright/inverted, magnified/reduced), and maybe like a diagram of some sort for the types of images produced at different distances from the mirror or lens (like form the focal point or radius of curvature). I think it would really help. I am just having trouble drawing out the images and diagrams.
Relevant Equations
Thin Lens Equation
Magnification Equation
Here is what I have:

One thing that helps is to realize that concave mirrors act the same as convex lenses; the difference being that the images are on opposite sides of them.

Same holds for convex mirrors and concave lenses.

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
