Waves

Path Difference and Interference

Product Code: OPT0011

Price: 4 USD ( Order Form )

Files: 6 movies (512 X 256 pixels).  Each movie is provided in AVI and Quicktime format.

Description:  This set of 6 animations is designed to help explain how the path difference between two waves affect their interference.

First animation: Both wave sources are in phase, the path difference increases slowly.

Second animation: Wave sources are 180° out of phase with each other, the path difference increases slowly.

Third animation: Both wave sources are in phase, the path difference equals the wavelength (constructive interference).

Fourth animation: Both wave sources are in phase, the path difference equals half  the wavelength (destructive interference).

Fifth animation: Wave sources are 180° out of phase with each other, the path difference equals the wavelength (destructive interference).

Sixth animation: Wave sources are 180° out of phase with each other,  the path difference equals half  the wavelength (constructive interference).
