3B50.40 - Moiré Transparencies
Code Number:
References:
3B50.40
Demo Title:
Moiré Transparencies
Condition:
Good
Principle:
Wave Phenomenon
Area of Study:
Acoustics
Equipment:
Interference Models for Overhead Projector, and Moiré Patterns.
Procedure:
Tape one sheet of the interference models to the overhead projector. Moving another sheet over this one will produce a visible interference front.
The other Moiré patterns with the accompanied pictures, will give a variety of different effects. These effects will include 3-D and simulated motion.
