• Read pages 520-521
• Do #1, 2, 7 on page 550

• Read Section 14-2 (note: the book uses different variables)
• Do #16, 17, 19, 20, 21, 22 on page 551
• Find a mirror and try to answer the question:  "can you see more of yourself if you step away from the mirror?"

• Throughout the weekend, find examples of convex mirrors and concave mirrors around you.  Make note of where you found the mirror and what it is used for (note: the mirror does not need to be used as a mirror!!  It could just be a piece of metal that is curved that acts as either a convex or concave mirror).  Just as we did in class, play around with moving closer and further away from the "mirror" and observe what happens to the image.  I will ask you to turn your observations in on Monday.

• Do problems #23-26 on page 551

• Read and take notes about drawing ray diagrams (note: the book mentions the "mirror equation" - we will discuss this later): 

           a) concave mirrors:  end of page 533 and page 534

           b) convex mirrors: page 537

• Do #1 from the activity sheet - draw ray diagrams for the three object positions for the concave mirror.  If you need it, you can download extra copies of the ray diagram sheet I handed out today here.

• Finish #1 from the activity sheet- draw the ray diagram for the convex mirror
• Do #2 from the activity sheet
• For more practice, continue working on the curved mirror worksheet.  You may want to try the diagrams.  Whatever you feel you need extra practice on.  I have put the solutions to this worksheet in the homework solutions folder. 

• Do problems on Pages 551-552 #30, and 34b,c, and 36
• NOTE:  For #34b,c and 36, recall that R = 2f.  #34b,c are two part problems.  You must first solve for ____ (I'll let you figure it out!) before solving for the magnification. 
• If you are still struggling with ray diagrams, make up a couple of problems and practice (this is not required - just make sure you know how to do the diagrams and come get help if you are still confused).  Use the diagrams in the book for reference.  Do a couple with notes and help from the book, then do a couple without notes.
• LAST NOTE:  Review our notes from class about when the image distance should be negative or positive and when the forcal length should be negative or positive.  This will be important for #36.

• Read 15-1 for review of what we discussed today
• Do problems on page 589 #39, 42, 50

• Do Practice with Refraction worksheet
• Do problems on pages 587-590 #10, 14, 57a

• Read 15-3 - Total internal reflection section
• Do #1, 2, 4 on page 582
• Do #38 on page 589

• Read 15-2 - pages 568-573 - read carefully and take notes
• Use tonight to review what we have done so far - mirrors, snell's law, TIR

• Do the Follow Up to "Focusing on Lenses" activity - #1 and #2 for the converging lens (we will learn how to deal with the diverging lens tomorrow)

• Study table 15-3 (converging lens ray diagrams) and figure 15-9 (diverging lens ray diag)
• Do problems on page 576 #1, 2, 3 (recall if two lenses both have a focal length of 10 cm, f = 10 cm for the convering lens and f = -10 cm for the diverging lens)
• Finish the Follow Up to "Focusing on Lenses" activity - #1 and 2 for the diverging lens

Start to review:  with this, I'd like you to work on drawing diagrams for both lenses and mirrors

• What type of image do you get for a concave mirror if (a) do>f and (b) do<f? Is the image bigger or smaller than the object for the two situations?  Where is the image located (in front of or behind the mirror) for the two situations?  Draw a ray diagram for the two situations.
• What type of image do you always get for a convex mirror?  How does the size of the image compare to the size of the object?  Where is the image located (in front of or behind the mirror)?  Draw a ray diagram for this situation.
• What type of image do you get for a converging lens if (a) do>f and (b) do<f? Is the image bigger or smaller than the object for the two situations?  Where is the image located (same side as the object or opposite side) for the two situations? Draw a ray diagram for the two situations.
• What type of image do you always get for a diverging lens?  How does the size of the image compare to the size of the object?  Where is the image located (same side as the object or opposite side) for this situation? Draw a ray diagram for this situation.
