M4-23: SOAP FILM INTERFERENCE - ROTATING HEMISPHERE
- ID Code: M4-23
- Purpose: Demonstrate circular soap film interference patterns.
- Description:
The rotation of the soap film produces a radial thickness gradient, which leads to rings of color around the soap film. The center becomes black when it is less than one-quarter wavelength thick.
