Homework Help Overview

The discussion revolves around the characteristics of images formed by a concave mirror when an object is placed at its center. Participants are exploring the relationships between object position and image size, orientation, and type.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants are analyzing ray diagrams and questioning the accuracy of their interpretations regarding image characteristics. There is an ongoing dialogue about the size and orientation of the image based on the object's position.

Discussion Status

The discussion is active, with participants providing feedback on each other's ray diagrams and interpretations. There is recognition of potential errors in reasoning, and some participants are reconsidering their initial conclusions about the image characteristics.

Contextual Notes

Participants are navigating between concepts related to concave mirrors and convex lenses, indicating some confusion that may affect their understanding of the problem context.

Homework Statement



What is the relative size, orientation, and type of image from an object placed at the centre of a concave mirror?


Homework Equations



I drew a ray diagram for this.


The Attempt at a Solution



The image will be erect, the same size and real.

That seemed too easy. Am I doing something wrong here?

Take another look at your ray diagram because one of those statements is incorrect
 
Okay. I think I know what I did wrong - the image should be smaller, not the same size...I think...
 
no, if the object is in the center, it would in fact be the same size. Did you draw one ray eminating from the object horizontally, hitting the mirror and passing through the focus? And another passing through the focus reflecting off the mirror and traveling horizontally? Easiest pair, imo.
 
wait, you're right, I drew a diagram for a convex LENS. My mistake.

So my image is going to be erect, the same size, and real.
 
that's exactly what you said in your original post... You still need the info for a concave mirror right? If so, one of those is still incorrect
