| 6C10.10 -Single Slit and Laser |  | This demonstration shows the diffraction pattern of laser light passing through a single slit. |
| 6C10.15 - Adjustable Slit and Laser |  | Using a variable width slit, you can show what happens to the diffraction pattern when the slit size is varied. |
| 6C20.10 - Laser and Diffraction (Poisson's Bright Spot) |  | This demo shows that laser light can diffract around an object such as a razor blade or pin head. |
| 6C20.15 - Razor Blade Diffraction |  | |
| 6C20.20 - Thin Wire Diffraction (strand of hair) |  | A narrow opaque object will create a diffraction pattern that may be used to measure the width of ... |
