					              Plane Mirror Images: Individual Pre-Lab Predictions
Circle responses to complete these statements with respect to you viewing your own FULL-LENGTH IMAGE in a vertically
positioned plane mirror in relation to your HEIGHT and DISTANCE AWAY FROM THE MIRROR.

When standing the exact same distance from the mirror,
the smallest mirror you can use and still see your                How do you know?
full-length image will be …
    a. longer than
    b. shorter than
    c. the same size as
the smallest mirror a shorter person can use in order to
see his/her full-length image.

The top of your smallest length mirror should be …                How do you know?
   d. at a higher position than
   e. at a lower position than
   f. at the same position as
the top of the smallest length mirror for the shorter person
who is standing the exact same distance from his/her mirror.

Pre-Lab:

Each group must complete and hand in their Pre-Lab Predictions before beginning this investigation.

Learning Tasks:

You may not use your computer or any resources other than those supplied by the instructor during this
activity. You may only discuss procedures, data, results, and/or conclusions with members of your own group.

1. Use the available resources to determine a plane mirror’s a) minimum length and b) vertical placement on a wall
   necessary for one to see his/her own full length image when standing in front of the plane mirror.

2. Determine if/how this minimum mirror’s size and placement on the wall depends on an individual person’s height and
   distance away from the mirror.

3. Include a complete explanation of your findings using the behavior of
   light to justify your answers. This explanation should include diagrams.

4. Hand in your group’s Investigation Summary and Final Summary.

                             Plane Mirror Images: Final Summary
Based on results from your investigation, circle responses to complete these statements regarding a person viewing
his/her full length image in relation to his/her height and distance away from the mirror.
When standing the exact same distance from the mirror,
the smallest mirror you can use and still see your             How do you know?
full-length image will be …
    a. longer than
    b. shorter than
    c. the same size as
the smallest mirror a shorter person can use in order to
see his/her full-length image.

The top of your smallest length mirror should be …             How do you know?
   d. at a higher position than
   e. at a lower position than
   f. at the same position as
the top of the smallest length mirror for the shorter person
who is standing the exact same distance from his/her mirror.



The minimum length of the mirror you can use and still see     How do you know?
your full-length image …
   g. gets taller
   h. gets shorter
   i. stays the same size
as you move farther away from the mirror.


The top of your minimum length mirror’s placement on the
wall …                                                         How do you know?
   j. gets higher
   k. gets lower
   l. stays at the same position
as you move farther away from the mirror.
