Moiré Pattern
Moiré Pattern
Moiré Patterns
Set up for Moiré Transparencies

 

Code Number: 3B50.40

Demo Title: Moiré Transparencies

Condition: Good

Principle: Wave Phenomenon

Area of Study: Oscillations & 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.
