Based on this sketch from Alex, I used Fusion to design the parts, lasercut them out of 1/8" plywood. All the little holes are for 1/8" dowels.

Shopping list

Last year, I saw that the servo arm that came with the servo was too short to fully flex the fingers. So I printed some new ones. They have different inside diameters, to determine which one would fit snugly on the servo shaft. D is the best, E,F too loose, A-C too small. [printed with PLA on the Prusa Mini, 100% infill, no supports.]

OPTICS

From here: about halfway down (Wed June 8)

Plan

  • Laser safety (Adriana)
  • intro to light as particle and/or wave (Crookes radiometer)
  • taking light apart and putting it back together:
     - make rainbows                     (flashlight, glass of water, prism)
    
    - diffraction slides (slides from box, CD?)
    - combining colors colored flashlights (add batteries), white screen
  • waves and interference demo (Hubert) part 3 of link
  • redshifts talk/activity (Greg) Link

    doppler activity (Hubert) Link

  • spectroscope (Asia)
  • measuring the wavelength of your laser (activity) Link
  • total internal reflection (activity) Link
  • Snell's law (activity) Link
From Laurie's notes:
Wednesday, June 7, 2023
Optics
12:15 to 12:30
Lasers and Laser Pointer Safety Adriana
12:30 to 1:00
The wave nature of light Laurie

   Ask “What is light?” (Energy – ability to do work – what is work, move stuff heat &
push around)
       Demo with Crooke’s Radiometer
       Show video of solar car
   Particle vs wave
       Definitions, wavelength, constructive/destructive interference
       Hubert’s strips
       Online ‘Ripple Tank’
       EM chart
             measure UV and IR with the laser meter and rainbow
             What part of the chart do you work with?
   Interference patterns – laser with diffraction grating
   Demo Interference pattern – cloth (Priscila Rosa did the hair measurement Tuesday)

1:00 to 1:30
Taking Light Apart and Putting it Back Together Laurie

    Discuss rainbows – demo with glass of water
    Make rainbows with triangular prism, collimator, and flashlight
    Make rainbows with diffraction grating and flashlight
    Demo how different colors bend differently (with lasers) time???
    Combine colors and make white with colored flashlights
      Talk about absorption of light
      Also use colored flashlights with prisms
      Discuss the Dress
“Step into the Rainbow” while playing with prisms

1:30 to 1:45 Break
1:45 to 2:15
Reflection and Refraction and Absorption and Scattering

   Demo reflection/refraction with laser refraction tank Laurie or someone?
   Total Internal Reflection (light guides, waterfall) Hubert
   Introduce 5-laser/prism boxes, look at focal length, etc.
   Index of Refraction
       Grow spheres in water Laurie
       Snell’s Law calculation Hubert
       Laser Microscope with dirty water Laurie
       Sky is blue tank (get the eggs) Laurie

2:15 to 2:45
Spectroscopy

   Infrared and UV examples
      Demo with IR/iPhone camera, UV
      Look at Various objects with UV lights
   RSpec Explorer with gas tubes and light tower
       Show spectroscope examples
       Use the spectroscopes they made as Tuesday night’s homework
   Fluorescence and phosphorescence demos
       Invisible ink pens and phosphorescent paper, write with blue laser
