Think Refraction

DoNow: What are the possible outcomes of light that hits a boundary? What laws are followed? (notes)

AIM: I can use key vocabulary to describe how to apply Snell's Law to predict the quantitative direction of refracted light paths and how to set-up the special situation used to calculate the critical angle for Total Internal Reflection, TIR. I can predict the direction of refraction with respect to the normal using density, index of refraction and apparent speed of the medium.
