refraction (concepts and calculations using the 3 equations, including Snell's Law)
Critical angle and Total Internal Reflection: calculation
calculations using Convex Lens Equation and Magnification Equation
Ray Diagram:   convex lenses + image characteristics
Ray Diagrams: concave mirrors + image characteristics
Ray Diagram:   plane mirror + image characteristics
optical devices:   you are expected to know a bit (ie: 2 marks) about each optical device you observed during the presentations.  This information will be taken from the handout provided by each group.
Be prepared for a major question on any optical device.
