Position Object for Inverted, Magnified Image with Concave Mirror

Click For Summary

Homework Help Overview

The discussion revolves around determining the position of an object in front of a concave mirror to achieve an inverted image that is magnified by a factor of 2.5. The subject area includes optics, specifically the behavior of concave mirrors and image formation.

Discussion Character

  • Exploratory, Assumption checking, Conceptual clarification

Approaches and Questions Raised

  • Participants explore the basic equations related to spherical mirrors and image formation, questioning how image size relates to object and image distances. There is a discussion about the implications of image size remaining constant regardless of the object distance.

Discussion Status

The conversation is ongoing, with participants questioning assumptions about image size and its dependence on object distance. Some guidance has been offered regarding the relationship between object distance, image distance, and image size, but no consensus has been reached.

Contextual Notes

Participants are navigating the implications of the focal length and the conditions necessary for achieving a specific magnification, while also addressing potential misconceptions about image size stability.

Where do you put an object in front of a concave mirror of focal length 10 cm to produce an image that is inverted and 2.5 times greater than the object?

I have no idea how to solve this.. help..

What are the basic equations describing spherical mirrors and image formation?
 
i only know the equation on how to solve for the focal length

f= (pq)/(p+q)

where p is the distance of the object from the mirror and q as the distance of the image from the mirror.
 
Good. And how does image size relate to p and q?
 
i come to think of it, the image size does not change no matter what value of p and q is.

could that mean that there is no way that the image will be 2.5 times greater than the object?

You'd better check that assumption. As you move the object around, the position and size of the image will change.
