4/29 Physics update and homework due 5/6

Hi folks,

Today we continued our discussion of optics by taking a deeper look at concave (divergent) lenses and by working a bit with mirrors.  We will do more with mirrors next week.

Homework for next week:

Read the text pages 442-459

Do questions #'s 1 - 26 on page 460

Be sure to understand ray drawings for convex and concave lenses.  There will be a quiz next week.  This website does a nice job explaining how to do ray diagrams for concave lenses if you need it.  http://www.physicsclassroom.com/class/refrn/Lesson-5/Diverging-Lenses-Ray-Diagrams
