Ray diagram diverging lens both object and image virtual

Click For Summary
The discussion focuses on creating a ray diagram for a diverging lens where both the object and image are virtual, specifically when the focal length (f) and object distance (p) are both negative, with p being less than f. Participants express difficulty finding resources or textbooks that illustrate this specific case. Suggestions include watching educational videos for guidance and utilizing online resources like HyperPhysics for ray diagram construction. The conversation emphasizes the need for clear visual aids to understand the behavior of light through a diverging lens in this scenario. Overall, the thread seeks to clarify the process of drawing the ray diagram for virtual objects and images with a diverging lens.

Homework Statement


Draw the ray diagram of the case of a diverging lens where both object and image are virtual, that is ##f<0## , ##p<0## with ##p<f##

Homework Equations

The Attempt at a Solution


I did not find this particular case of ray diagram in any textbook so I would like to know where to find it or how to build it on my own.

Watch this .
It might give you ideas you can apply to the diverging lens.
 
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?
