Homework Help Overview

The discussion revolves around the effects of convex mirrors on image location and size, specifically involving a scenario with a woman standing in front of a convex mirror. The problem includes parameters such as the woman's height, distance from the mirror, and the mirror's radius of curvature.

Discussion Character

  • Exploratory, Conceptual clarification, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the use of ray diagrams and the mirror/lens equation to determine the image location and size. There are inquiries about the correctness of calculations and the index of refraction related to light speed in a material.

Discussion Status

Some participants are seeking clarification on the correctness of their attempts, while others provide resources and suggestions for further investigation. Multiple interpretations of the problem are being explored, particularly regarding the index of refraction and its relevance to the discussion.

Contextual Notes

There is a mention of a second question regarding the index of refraction, which may not be directly related to the convex mirror problem. Participants are encouraged to refer to textbooks and external resources for additional information.
