First, a reminder: your homework, to answer the question "Why does a pencil look bent when partially submerged in water?" is due today. Going over the answer is the first thing on our agenda.
Next, we discuss total internal reflection:what it is and examples. Partial notes are below.
Finally, we start working on tonight's homework, Concept-Development 29-3. This is due tomorrow.
