6C10.12 - Diffraction - Laser and Cornell Plate

Code Number:
Demo Title:
Diffraction - Laser and Cornell Plate
Diffraction of Waves
Area of Study:
Optics, Astronomy
Helium-Neon Laser (2 to 5 mw.), Optics Bench, Cornell Plate.

The Cornell plate has a explanation sheet that goes with it telling things like slit width, slit spacing, and number of slits.  Choosing the appropriate slit in the dark can be aided by shining a flashlight through the plate during alignment.
