Wave Behavior
2
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
5
Examples: Colors
6
Examples: Ripples
7
Examples: Ducks ?
8
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
11
Behavior 3: Diffraction ~ waves will bend when they hit a barrier
12
Example: Break wall
13
Example: CD’s
14
Head light with no diffraction
Example: Eyes Head light with no diffraction
15
