We continued taking "Light Interaction with Media" notes. We learned Fermat's Principle and Snell's law of refraction, and did a couple examples. For the rest of the period we were working on the "Refractive Index" (P. 197 lab). We had to draw two diagram, write out procedure, calculation and find error source.
Homework: finish the "Refractive Index" lab. Book work page 846, # 1- 11, 13-15,18. "Reflection & Refraction Questions" (P.199 lab).
Question of the day answer: The light will bend toward the the normal because the part of light that hit the second medium first will slow down while the other part is still traveling at a different speed in the initial medium. The light bends to take the shortest path to travel through the second medium.
