• Friday 5/20:  Turn in Equipotential Lab if not already.  Check off p. 695 and 703 HW and go over.  Types of electric circuits.  Try each type with lightbulbs.  Electric Power.  HW p. 710 1-2.

Remember that your Physics on the Edge Project is due next Thursday, 5/26.

The Week of 5/9-5/13

• Thursday 5/12:  Equipotential Lines Lab.  Van de Graaff generator demos.
• Friday 5/13:  Finish up unfinished business from Thursday.  Drawing Electric Field Lines. 

Answers to 14+15 Review Problems

1.  0.00000071 m (I can't figure out how to write sci. not. on this blog)
2.  M = - .48, so image is smaller, real, inverted
3.  p = 11.3 cm
4.  M = -20.0, so real and inverted
5.  23 degrees
6.  q = 170 cm, image height = 22 cm
7.  f = 200. cm, image is larger, virtual, upright
8.  refracted by 72 degrees

We will go over 9-14 in class

Rainbows and Human Eye (in library on 5/2/11)

Today I would like you to investigate how a rainbow is formed and how the human eye sees things, including how nearsightedness and farsightedness are corrected.  These concepts correspond to questions 12 and 14 on your 14+15 Review Sheet.  Both of these concepts will be short answer questions on your test on Thursday.

Instructions for Rainbows:
1.  Go to The Physics Classroom Link (bottom one)
2.  Go to Physics Tutorial
3.  Go to Refraction and Ray Model of Light (last one I think)
4.  Go to Lesson 4 and pick Rainbow Formation

Focus on the diagrams for how a rainbow is formed.  What 2 things happen to the light waves?  (think about the wave properties we have discussed).  Draw a picture of what happens in the water droplet.  If blue comes out on top of the droplet, why is it that red is on top of the rainbow that we see?  What 3 requirements are needed to see a rainbow?  (this is in the very last sentence of the rainbow section)

Instructions for The Eye:
5.  Follow previous instructions in Physics Classroom, but go to Lesson 6 (The Eye)
6.  Read about Anatomy (a), and Image formation (b)
7.  Read about farsightedness and correction (d)
8.  And nearsightedness (e)

Check out the eye diagram and how the human eye works.  How does the lens help focus to near and far?  What is wrong with a person's eye if they are farsighted and how is it corrected?  What is wrong with a person's eye if they are nearsighted and how is it corrected?

The Week of 5/2-5/6

• Monday 5/2:  Go to library.  Check off Lens HW and go over.  Look up rainbows and nearsightedness and farsightedness (instructions/questions will be on this blog).  Then do project research and/or LoggerPro graph for Snell's Law Lab. 
• Tuesday 5/3:  Turn in Snell's Law Lab.  Check off Critical Angle HW and go over.  Go over 14+15 Review Sheet. 
• Thursday 5/5:  Turn in 14+15 Review.  Take 14+15 Test.  When finished read 17.1 (pp 628-633).  Basic static electrics vocab.
• Friday 5/6:  Coulomb's Law.   HW p. 636 1-4. 

Due Date for the Physics on the Edge Project is Thursday 5/26.  Presentations will begin that day and go until we finish.
