Real 3D Image produced by concave lens

AI Thread Summary
The discussion revolves around identifying the correct image produced by a concave lens based on its focal length. The original poster initially selected answer A but later realized it was incorrect after analyzing a ray diagram. They clarified that the image is actually smaller, upright, and virtual, which aligns with the properties of a concave lens. The confusion stemmed from mistakenly considering it a convex lens. Ultimately, the poster acknowledged the error and expressed gratitude for the support received.

Homework Statement


Find the correct image produced by the concave lens. F is focal length.


Homework Equations


If an object is placed between F and 2F, the image will be inverted, real, larger and beyond 2F.


The Attempt at a Solution


I choose the answer A. Is it correct?

*Please refer attachments. Thanks!

Use a ray diagram to resolve this problem. The arrow head of the object is closer to the lens.

Thanks, the answer is B. I marked it wrong anyway! :/
 
My ray diagram suggests neither are correct?
 
Sorry, I think the image makes a little fuzzy. That arrow curve is perpendicular to the axis. In this image it looks it's headed towards i see.
 
The image is smaller, upright and virtual.

My bad. It's a convex lens :( Sorry, now only noticed.

I think now you can get it correct. Thanks for the support. :) It was in my exam paper and I chose the wrong one anyway! :(
