Professor Chemla will hold a review session Tuesday, Nov. 18 from 6-8pm in 141 Loomis Hall. Time permitting, he will go over the following selected problems from past exams: SP13 EXAM 2 #8-9, 15-16, 21-22, 23-25, and SP13 EXAM 3 #3, 7-8, 9-11, 13, 16-23. Please come to the review session having worked through these problems for a more effective review session. 



There was an error in one of the online CheckPoints to Lect. 23. The "Binary Suns" problem incorrectly stated that the pinhole should be made smaller; the correct answer is that the pinhole should be made larger (as discussed in lecture). This CheckPoint has now been corrected.

Two students noticed an error on the "apparent depth" slide #22 in Lect. 17. A corrected version of the ppt and pdf are now available on the schedule page.
