3B50.55 Interference Model
Painted wave trains on wood lath are attached to magnets for use on a steel blackboard in order to demonstrate double-slit interference. The magnets attached to the red wave trains are placed on the two “slits”. For ideal representation of constructive interference, place the third supporting magnet in the middle of “sheet”.
The blue wave trains represent a shorter wavelength of light and therefore demonstrate a different interference pattern.
See AJP 59, 857 for the full description.
Location: Red wave train on the door to Room 58; Blue wave train in the corner next to the door to Room 58
