This activity involves identifying the corresponding curved-mirror image for each of ten object positions.
Object Position 5
Object Position 4
Object Position 3
Object Position 2
Object Position 10
Object Position 1
Object Position 7
Object Position 8
There are 10 different object positions. For each position, identify the corresponding image. You can answer them in any order. Once you are successful at identifying the image, a gold star will appear next to the button.

A curved mirror is shown below. Each side has a reflective coating. An object is represented by a red arrow. Which blue arrow represents the corresponding image? Click or tap on the corresponding image. If there is no image, then click/tap on the No Image button.

Congratulations! You have identified the correct image. You can now … 1. Return to the main screen and try another question. or 2. View a ray diagram for this particular object position.

Sorry. That is not the correct image. Think about how object position affects the image location, orientation, and relative size. You can now … 1. Return to the diagram and try again. or 2. Visit a web page that thoroughly discusses this topic.

Ray Diagram: Starting from the top of the object, two incident rays are drawn to the mirror. The incident ray that approaches parallel to the principal axis reflects through the focal point (F). The incident ray passing through F on the way to the mirror will reflect parallel to the principal axis. The image of the arrow-tip is located where these two reflected rays intersect.
Ray Diagram: Starting from the top of the object, two incident rays are drawn. The incident ray that approaches parallel to the principal axis reflects through the focal point (F). The incident ray that strikes the center of the mirror reflects according to the law of reflection. Since the two reflected rays are traveling parallel to one another, they will never intersect. This means there is no image for this situation.

The incident ray passing through F on the way to the mirror will reflect parallel to the principal axis. The image of the arrow-tip is located where the extensions of these two reflected rays intersect.
Ray Diagram: Starting from the top of the object, two incident rays are drawn. The incident ray that approaches parallel to the principal axis reflects in line with the focal point (F). The incident ray heading towards F on the way to the mirror will reflect parallel to the principal axis. The image of the arrow-tip is located where the extensions of these two reflected rays intersect.
