1. Task 1: 2 mirrors and a nail- observations At 180° we can see 2 nails. The reflection of the nail was repeated 3 times inside of the mirrors. We saw 9 nails at the smallest angle created by the mirrors. The nails multiply by 2s, the closer the mirrors get. 8 nails appeared at the smallest angle. Looks like a hallway of nails. The more acute the angle between the mirrors, the more nails appear.

4. Task 2: Ray box and prism- Observations Light bends/changes angles as it comes out of the prism. Light bounces off the walls of the prism and shoots off color. – Red yellow and blue when standing up. – A rainbow is produced on the other side. Light is reflected 3 different ways inside of the prism.

5. Task 2: Conclusions

6. Diagram

7. What we are wondering Why does the prism produce a rainbow? What does the nail appear to curve in task 1? What happens inside of the prism that makes it reflective?

8. What is Reflection? Reflection is the rebounding of light that occurs when a light ray hits a different medium and bounces back. The angle at which it bounces back is = to the angle at which it hit the surface.

11. What do we believe is happening?

12. Incident Rays extend from the object onto the mirror. The image is actually produced behind the mirror at an equal distance as the true object (virtual image).

14. Diffuse Reflection Some surfaces appear to be smooth, however they are often uneven and rough if you look under a microscope.

15. Diffuse reflection In this case the reflection does not respect the laws of reflection.
