Conservation of Energy in Waves

9th - 10th
High school teacher Kate Nichols explains that wave energy is equal to the amplitude of a wave. Looks at different scenarios where we may notice that wave energy is being conserved or not. The conversion of wave energy into another type...

Bozeman Science: Physics: Wave Interference

9th - 10th
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

9th - 10th
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...

7 Active Technology Solutions: Interference and Law of Conservation of Energy

9th - 10th
It appears that energy is destroyed at the points of destructive interference and created at the points of constructive interference. So, the law of conservation of energy appears to be violated. But this is not correct. The energy is...
