APPLYING PRACTICES Constructing Ray Diagrams To locate and describe the image formed by a lens or a mirror, you can construct a ray diagram or use thin lens and mirror equations. You will find detailed ray diagrams and both equations in your textbook Convex Lens 1. Construct a ray diagram to determine the approximate location and size of the image formed by the convex lens. 2. In the example above, the object is 6.0 cm tall and is 12.0 cm from the lens. The focal length of the lens is 8.0 cm. Use the thin lens equation to obtain numerical information about the image distance and image size.

Construct a ray diagram to determine the approximate location and size of the image formed by the concave mirror. 4. In the example above, the object is 2.0 cm tall and is 6.0 cm from the mirror. The focal length of the mirror is 2.0 cm. Use the mirror equation to obtain numerical information about the image distance and image size.
