Bozeman Science: Physics: Wave Interference
Paul Andersen explains how waves interact with objects and other waves. When a wave hits a fixed object, it will be reflected and inverted. When a wave hits a free object, it will be reflected without being inverted. [6:24]

Bozeman Science: Physics: Interference Patterns
In this video, Paul Andersen explains how constructive and destructive interference can create interference patterns. Interference patterns can be created by all types of waves, including water, sound, and light. A classic experiment...

Khan Academy: Thin Film Interference Part 1
Thin-film interference occurs when light waves reflecting off the top and bottom surfaces of a thin film interfere with one another. This type of interference is the reason that thin films, such as oil or soap bubbles, form colorful...
