This demonstration of diffraction shows the behavior of light when passing through a slit on the order of the slit's wavelength. A diffraction pattern can be viewed on the screen.
Setup:
Place the ring stand on the lab table with laser and single slit plate. Setup a viewing screen in front of this system. Connect the webcam to the projector and set it up to show the viewing screen. Align the laser to hit the single slit.
Turn on the laser and view the diffraction pattern on the viewing screen.
Notes:
This can be done with the red, green, or violet laser.
Be careful not to point the laser at anyone or look directly into the beam.
May need to be performed in a darkened room.
