2. • Identify the images formed by the different types of mirrors
and lenses
• Predict the qualitative characteristics (orientation, type and
magnification) of images formed by mirrors and lenses
• Apply ray diagramming or ray tracing in describing the
characteristics of images formed by mirrors and lenses.
• Enumerate the properties and characteristics of mirrors and
lenses with their uses as optical instruments.
4. Is an object or device that reflects light. Mirrors are
typically made up of a glass coated with metal
amalgam (alloy) that reflects a clear image.
5. Is another optical device that transmits and refracts
light. A lens is usually made up of a glass or transparent
materials with curved sides. The curved sides of the lens
either or the beam of incident light.
6. Both mirrors and lenses form images. Mirrors
produce reflected images. Images formed by
mirrors and lenses depend on the type used
and location of the object. The characteristics
of the images are in termed of:
7. The image formed can either be .
The image formed can be
The image formed can either be
8. Is the systematic process of tracing or
diagramming rays in forming an image formed.
The following are helpful terms and notations
for ray tracing and diagrams:
19. Do you have:
Graphing paper
Colored pencil
Ruler
Drawing compass or protractor
Working brain
20. Do the following:
Case 1: The object is located beyond the center of curvature
Case 2: The object is located at the center of curvature
Case 3: The object is located between the center of curvature
and focal point
Case 4: The object is located at the focal point
Case 5: The object is located in front of the focal point.
21. Case 1: The object is located beyond the center of curvature
C f
22. Case 2: The object is located at the center of curvature
C f
23. Case 3: The object is located between the center of curvature
and focal point
C f
24. Case 4: The object is located at the focal point
C f
25. Case 5: The object is located in front of the focal point.
C f
26. STEP 1: Draw a ray, starting from the top of
the object, parallel to the principal axis and
then reflect passing to the focal point (f).
27. STEP 2: Draw a ray, starting from the top of
the object, passing to the focal point (f) and
reflects parallel to the principal axis.

convex mirror. Determine the height,
orientation, type and the new location of the
image.
