Student Exploration: Ray Tracing (Mirrors) /15
Directions: Follow theinstructions to go through thesimulation. Respond to thequestions and prompts
in theorange boxes.
V ocabulary: concave mirror, convex mirror, focal point, magnification, real image, reflect, virtual image
Prior Knowledge Questions (Do these BEFORE using theGizmo.)
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 thefront of thespoon (the side where thefood sits). What do you see?
I see that my head is small and that I’m upside down and also my face is distorted.
The front of a spoon is an example of a c oncave mirror.
2. What do you see when you look at yourself in theback of a spoon?
I see that my head is small and that I’m right side up and also my face is distorted.
The back of a spoon is an example of a c onvex mirror.
Gizmo Warm-up
The Ray Tracing (Mirrors) Gizmo shows a side view of a
light bulb positioned to theleft of a mirror. Light rays
passing from thelight bulb to themirror are shown.
To begin, select theConcave mirror. Turn on Colorize
lines. Under Show lines, turn off theCentral line and
theLine through focal point so that only theParallel
line is showing.
1. The blue dot in front of themirror is thefocal point of themirror. Move thelight bulb on theleft around.
What is always true about theray that is reflected from theparallel ray?
The reflected ray always passes through the focal point.
