Wave Behavior
Behavior 1: Superposition~ 2 or more waves adding together to form a resultant wave. (Waves will interfere with each other) Constructive Interference ~ waves add together and their resultant amplitude increases Destructive Interference ~ waves add together and their amplitudes cancel each other.
Constructive Interference
Destructive Interference
Examples: Colors
Examples: Ripples
Examples: Ducks ?
Behavior 2: Reflections Reflection on a fixed end: reflected wave is opposite (upside down) Reflection on a free end: reflected wave is on the same side demos
Fixed End
Free End
Behavior 3: Diffraction ~ waves will bend when they hit a barrier
Example: Break wall
Example: CD’s
Head light with no diffraction Example: Eyes Head light with no diffraction
