UNIT 08  Optics 
EXPECTATIONS  Before we start this unit you should:

LEARNING TARGETS: → I will be able to demonstrate understanding of the Law of Reflection by applying principles of retroreflection in our everyday life → I will be able to demonstrate understanding that all <normal matter> in the Universe does at least one of the following:
→ I will be able to trace light rays moving into, through, and out from a convex lens → I will be able to trace light rays moving into, through, and out from a concave lens → I will be able to trace light rays moving into, through, and out from a concave mirror → I will be able to utilize the relationship between the speed of light in one medium compared to the speed of light in a neighboring medium to calculate the index of refraction of that medium: c/v = n
→ I will be able to utilize Snell's Law to analyze refraction using the following formula: v_{2}sinθ_{1} = v_{1}sinθ_{2} where v_{1} and θ_{1} are the velocity and angle of the incident light ray and v_{2} and θ_{2} are the velocity and angle of the refracted light ray (NOTE: This is NOT the precise form of Snell's Law but it is a variant that you need to be very comfortable with) 
PHENOMENA:

There Once Was a Lady Named BRIGHT Who Traveled FAR FASTER than Light She Set Out One Day (In a relative way) And Came back the PREVIOUS night!
