Objective: Determine the behavior of the object using the diagramming (principal-ray diagram).

Materials: Bond paper, pencil, ruler

Procedure:

Given. Case: The object is behind the center of curvature.

` a. Mirror is concave

1. Height of the object is 3 cm
2. The center of curvature is 10 cm
3. The focal point is 5 cm
4. The location of the object from center of curvature is 8 cm.

*Draw the principal ray diagram using the given to find the height of the object, location of the image from center, orientation of the image (ether upright or inverted). *Follow the pattern the rules of making diagram.
