Optics
*activities available as photocopies

This unit is set up a little differently than the others. I have included online lessons and virtual labs for this unit. These virtual labs are great, but are no substitute for the real thing. You are expected to do several similar labs using real mirrors and lenses in the classroom. The lab manuals for "Conceptual Physics", "Modern Physics" and other texts have many good labs on reflection, refraction and optics. The guide to the "Optics Discovery Classroom Kit" has some activities to get you started also. You may also wish to design your own labs based upon these labs or the virtual ones whose links follow.

ACTIVITIES ON Reflection & Mirrors

	*Law of Reflection Tutorial* Print out the worksheet for this online tutorial.		Try This Set up a box like the one pictured. What do you see looking down from the top, before and after you clap chalk dust in the box? Why is outer space black even though it has so many stars?
	*Law of Reflection Lab* *Print out this worksheet and follow the link at the top for this virtual lab exercise.**		*Images in a Plane Mirror* *Print out this worksheet and follow the link at the top for this virtual lab exercise.**
	*Mirrors and Images Virtual lab on multiple images.		*Curved Mirrors* Print out this worksheet and do the interactive tutorial on curved mirrors.
	*Image Formation: Ray Tracing Basics* FYI - use these rules with both mirrors and lenses.		*Curved Mirror Lab Images* *Print out this worksheet and follow the link at the top for this virtual lab exercise.**

ACTIVITIES ON Refraction & Lenses

	*Refraction of Light* Great info with interactive java tutorials (take notes on what you discover).		*Refraction Tutorial* Print out this worksheet and follow the links to answer the questions.
	*Refraction Labs* Print these out and do the lab with equipment in the classroom. *1. Refraction Action* *2. Snell's Law Lab*		*Virtual Labs: Snell's Law* *1. Refraction Analysis* 2. Refraction Problems: Snell's Law 3. Law of Refraction
	*Total Internal Reflection* Print out this worksheet and follow the links to answer the questions. This also includes a virtual lab.		*Intro to Lenses* Great info with interactive java tutorials (take notes on what you discover).
	*Tutorials* *4.Interesting Refraction Phenomena* 5.Image Formation by Lenses 6.The Eye		*Optics Bench* *Print out this worksheet and follow the link at the top for this virtual lab exercise lenses.**
	*Java Applets* Lenses and Ray Tracing Converging Lens Diverging Lens		*Finding Image Distances Using Ray Diagrams In class worksheet. Try these with actual lenses and compare results!
