3. Equipment supplied - 4 acrylic prisms- 8 combs - 3 color paddle sets- 16 polarized filters - 8 flexible mirrors- 8 flashlights - 8 dual convex lenses- 8 foamboards - 4 concave lenses- 40 pins - 8 diffraction gratings- 3 mirror supports - 16 D batteries

4. Equipment needed -Index cards- Incandescent light bulb -White paper- Fluorescent light -Rulers- Candle -Colored pencils - Bunsen burner -Plastic wrap -Zip-lock bags -Colored pencils

5. Refraction Light changes velocity when it enters a different transparent medium Light slows when it enters material of higher refractive index Light speeds up when it enters material of lower refractive index

6. Refraction When light changes speed it bends; this is refraction All angles measured from normal (perpendicular) to interface of surfaces

7. Snell’s Law n₁sinƟ₁ = n₂sinƟ₂ n for vacuum is 1.000 n for air is 1.003 ? n for acrylic prism
