1. Decide who is going to study geometric optics and who is going to study Physical optics.
2. Begin taking and organizing notes for all parts under your specific area. Use these websites to start:
Snell's Law explanation
- Lens makers equation
all of these videos are great!

(from 2010 trial events)
The nature, properties and behaviors of waves are discussed and illustrated; the unique nature of a standing wave is introduced and explained.
Light Waves and Color
The behavior of light waves is introduced and discussed; polarization, color, diffraction and interference are introduced as supporting evidence of the wave nature of light. Color perception is discussed in detail.
Reflection and the Ray Model of Light
The ray nature of light is used to explain how light reflects off of planar and curved surfaces to produce both real and virtual images; the nature of the images produced by plane mirrors, concave mirrors, and convex mirrors is thoroughly illustrated.
Refraction and the Ray Model of Light
The ray nature of light is used to explain how light refracts at planar and curved surfaces; Snell's law and refraction principles are used to explain a variety of real-world phenomena; refraction principles are combined with ray diagrams to explain why lenses produce images of objects.

No, it's not red - it's green
Okay, just about everyone has a red laser pointer. Heck, we even sell a
here at ThinkGeek. But, we're pretty sure you want to be a superior geek - and doing it with a green laser is the way to go.
This pointer is significantly brighter (about 50 times) than a red laser pointer and because of its unusual color it is much more noticeable. I mean come on, a 532 nm green laser wavelength is obviously superior to a laughable 650 nm red laser wavelength. And unlike a red laser, the green beam itself can be seen in mid-air in dark conditions, not just the laser beam dot. This allows the green laser pointer to be used for pointing to star constellations (skypointing) and also just generally look cool as hell. The green laser beam dot can be seen at much greater distances than with a red laser pointer.
Since green direct injection laser diodes aren't readily available, this pointer is based on the use of Diode Pumped Solid State Frequency Doubled (DPSSFD) laser technology. A high power IR
laser diode at 808 nm pumps a tiny block of Nd:YVO4 generating light at 1,064
nm which feeds a KTP intracavity frequency doubler crystal to produce the green beam at 532 nm.
Features of this unit include:
Very bright green laser at 532 nm wavelength
Output power of <5mW (Class IIIa Laser Product)
Range of approximately 9,000 ft (2600 m) in darkness
1.1 mm beam diameter at source
Momentary push button switch
Solid, heavy duty construction
Constant wave output (as opposed to pulse output)
Takes 2 "AAA" batteries (not included)
Can be used for skypointing, projection on low clouds, signaling, highlighting potential explosives
Dimensions: 5.6" x .5" dia
Available in or Silver color

Warning: Green lasers are very powerful. Pointing at aircraft may land you in jail. Without a Monopoly card to get you back out. Use it wisely.
