Optical Instruments I: Optical Element

Click For Summary
The discussion revolves around matching seven diagrams of optical elements with their corresponding types: Plane Mirror, Concave Mirror, Convex Mirror, Converging Lens, and Diverging Lens. The user initially provided their answers but expressed uncertainty about their accuracy, particularly regarding diagram #4, where the image is not inverted. Other participants pointed out this detail, suggesting it could indicate a specific type of optical element. The conversation highlights the importance of analyzing image characteristics, such as inversion, to correctly identify optical elements. Overall, the thread emphasizes collaborative problem-solving in understanding optical instruments.

Homework Equations


Ray Diagrams

The Attempt at a Solution


1) Concave Mirror
2) Plane Mirror
3) Diverging Lens
4) Converging Lens
5) Concave Mirror
6) Converging Lens
7) Converging Lens

I can't figure out where I'm making my mistake. Can anyone help me?

I have not looked at all of them closely, but notice in #4 that the image is not inverted. Does that help?

Thank you, I missed that one.
 
Sure, glad to help!
 

Thread 'Magnitude of buoyant force in fluids of different densities'

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?
