Description:
Look at a diffraction pattern through a lens to reveal a new pattern!
Location:
- X-Ray Crystallography Kit (L-3)
- Lens Holder (found in wooden Laser Optics Kit box; M3)
- Lens Holder Stand (Dr. 104)
- Green laser
- 2 lab jacks
Setup: Use the lens holder from the Laser Optics Kit to hold one of the x-ray crystallography slides. There are a lot of different patterns available – L is for Escher Lizard, H for horse, and a few others. Shining the laser through the pattern uninterrupted creates an indiscernible dot pattern like this: [File|crystallography2.png] [File|crystallography1.png]
But, when you shine the laser through the lens included in the x-ray crystallography kit first, the pattern is revealed: [File|crystallography5.png] [File|crystallography3.png]
Try it with different patterns and different spacing to improve the focus.
