## Detail Page

This is an interactive homework problem on the topic of ray optics.  It presents this scenario:  a distant object forms an image 2.8 meters in front of a slightly curved mirror.  With only this information, students must determine the radius of curvature of the mirror.

The problem was developed by a physics education researcher to help students with concept formation and strategic problem solving skills.  It is accompanied by a Socratic-dialog "help" sequence that guides users through a full conceptual analysis before attempting the mathematics. It is part of a larger collection  developed by the Illinois PER Group.

This resource is part of a Physics Front Topical Unit.

Topic: Nature and Behavior of Light
Unit Title: Ray Optics -- Reflection and Refraction of Light

This is a companion homework problem to the one above, created by the same author.  Here is the scenario: A distant object forms an image 2.8 meters in front of a curved mirror.  With only this information, students must figure out the radius of curvature of the mirror.  This problem also contains ray diagrams to help students visualize the situation as they are guided through each step of the problem-solving.
