Homework Help Overview

The discussion revolves around a problem involving a convex lens, specifically focusing on locating the image produced by the lens and describing its characteristics. Participants are exploring concepts related to optics.

Discussion Character

  • Exploratory, Conceptual clarification, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the need to determine the focal length of the lens and question whether the image is real or virtual, as well as its orientation and size relative to the object. There is mention of using graphical methods to locate the image based on provided diagrams.

Discussion Status

Some participants have offered guidance on the characteristics that need to be described, such as whether the image is real or virtual, upright or inverted, and the magnification. The original poster has acknowledged the input and provided some characteristics of the image.

Contextual Notes

There is a mention of a graphical problem with diagrams provided, which may influence the interpretation of the image characteristics. The discussion also hints at the need for numerical calculations related to magnification.

I have to complete a problem about locating an image for a convex lens but I'm having trouble with it. I tried it out, but I can't complete it. Can someone help please?

Locate the image for the convex lens below. Use any two rays to do so. Give the characteristics of the image.

I'm having trouble particularly with describing the image. I'll attach the picture of the lens and my answer to it.

you need to work out the focal length of the lense, try looking in an optics book.
 
Is the image real or virtual? Is it upright or inverted? How much larger is it than the object?

No, it's a graphical problem. The first diagram shows the focal points and the location of the object, so he has enough information to locate the image, which he did in the second diagram.

All he has to do now is describe the key characteristics of the image. Usually this means saying whether it's real or virtual; upright or inverted; enlarged or reduced in size. Maybe calculate the numerical value of the magnification by measuring the sizes of the object and image.
 
okay, thanks a lot guys.

So it's real, inverted, and M>1
