Student Exploration: Ray Tracing (Mirrors) Vocabulary: concave mirror, convex mirror, focal point, magnification, real image, reflect, virtual image Prior Knowledge Questions (Do these BEFORE using the Gizmo.) For these questions, it would be helpful to have a metal spoon on hand. If you don’t have one, try to imagine looking at yourself in a spoon. 1. Look at yourself in the front of the spoon (the side where the food sits). What do you see? I’m upside down. The front of a spoon is...

Week 11 Online Lab: Ray Tracing Mirrors Gizmo Explore Learning Gizmo: Ray Tracing (Mirrors) For this assignment, you'll use a Gizmo at the Explore Learning web site. Before you begin:  Be sure you have read the assigned reading for the week.  You may want to print this document so that you can note observations as you work with the gizmo. Later, you can type your answers into the Word document and upload it with this assignment form.  All questions to answer are contained in th...
