• Homework-Due Thursday, Dec. 4

• Reflection-Task 1

1. Carefully draw a picture of a yourself standing in front of full-length
   mirror on a vertical wall. Draw a ray diagram representing the light rays
   coming from the your feet and your head as seen by your eyes.
2. Include a brief discussion of any physics principles you apply as you draw
   this diagram.
3. Based on the diagram, how long does the mirror need to be in order for
   you, a person of height hand standing a distance rfrom the mirror, to be
   able to see your whole reflection? Sketch the location of such a mirror on
   the wall. [Hint: the your eyes are a distance dbelow the top of your head.].
   How is the length of the mirror related to the distance ryou are standing
   from the mirror?

• Bending Light-Task 2

1. Complete the numerical analysis on the bending light page.
2. Use the InfoMall to find a reference to Snell's Law and give the citation.
3. Compare your numerical results from your analysis of bending light to the
   theoretical results from Snell's law.
