1. - Review how refraction and reflection govern the behavior of light at boundaries - Observe demonstrations of light and color - Discover how lenses of different types interact with light and are used to project images ; compare and contrast a lens camera with a pinhole camera TODAY’S OUTCOMES: BEHAVIOR OF LIGHT

2. round water bottle (top view) screen Light incident on a round, clear water bottle passes through it, but the light beams refract “inward” at both the surface entering and the surface leaving the water bottle. Thus, the light does not illuminate a surface beyond the bottle in a uniform manner - some areas will be brighter than others. 15. Explain, what does refraction have to do with clear objects making shadows? right edge of shadow left edge of shadow bright center, darker edges

3. 16. A laser beam is directed towards a prism, as shown. Three visible light beams result: A) light that is reflected from the front surface, B) light that enters the prism, travels to a different surface of the prism, and leaves it; C) light that enters the prism, travels to a different surface of the prism where it is reflected, travels to yet another surface (perhaps the first one, again), and leaves there. Please draw in the path taken by these three beams (labeling them A, B, C).. A B C The emerging beam (C) is parallel to the incoming laser beam.

4. You can get both REFLECTION and REFRACTION of a light beam simultaneously at a boundary: thick piece of glass at an angle

5. You can get both REFLECTION and REFRACTION of a light beam simultaneously at a boundary: thin piece of glass at an angle

6. You can get both REFLECTION and REFRACTION of a light beam simultaneously at a boundary:

7. PRISM FROM LAST LAB: Many of you observed that if the light refracts at a sharp enough angle, that different colors of light emerge, instead of a white beam. You can see with a prism that white light, under the right circumstances, can be divided into different colors

8. - Both reflection and refraction can occur simultaneously at the boundary between materials - Refraction is the greatest at smaller angles of incidence - Light moving from air to glass/water refracts closer to a perpendicular line to the surface - Light moving from glass/water to air refracts further from a perpendicular line to the surface WHAT YOU ARE EXPECTED TO KNOW:
