NOTE TO STUDENTS: Based on your preferred learning style, you may choose to read theory first (Task #1) or explore with the simulation first (Task #2)
Task #1: Read: (a) Physics Classroom (continue for 3 more pages - to "Boundary Behaviour Revisited") (b) Refraction Notes
Task #2: Investigate the refraction of light by gathering data to complete this Refraction and Snell's Law Lab Data Sheet using the PhET Bending Light Simulation. (mins) Task #3: Enhance your understanding of refraction by downloading & viewing this Powerpoint on Refraction ( mins)
Task #4:
