Task 1: 2 mirrors and a nail-observations

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.

  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.

  2. Task 1 Conclusions • Because the angles reflected on each other, we are able to see more nails on both sides. • The mirrors are reflecting more reflections, which causes more nails to appear. • Mirror reflects light off the other mirror, sending it back where it started creating an infinite mirror.

  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 • Light Passes through the prism and comes out at an angle. • There is reflection on the inside of the prism because of the 3 lateral faces. • The light ray is made up of colors that we don’t see, and these colors are separated when they hit the prism (only at a certain angle).

  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.

  9. What do we believe is happening?

  10. 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).

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

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