by Bekki Johnson
1. Diffraction
1.1. Bending of a wave as it moves around an obsitcle
1.2. Waves come back together after passing an object
1.3. EXAMPLES
1.3.1. Fishing docks
1.3.2. River beds
2. Interference
2.1. Constructive
2.1.1. Two or more waves combine to produce a wave with a larger displacement
2.1.2. Waves join together
2.1.3. EXAMPLES
2.1.3.1. Music
2.1.3.2. Swings
2.2. Destructive
2.2.1. Two or more waves combine to produce a wave with a smaller displacement
2.2.2. Waves cancel each other out
2.2.3. EXAMPLES
2.2.3.1. Music
2.2.3.2. Trampoline
3. Standing Waves
3.1. Waves that appears to stay in one place
3.2. Cant see waves moving
3.3. EXAMPLES
3.3.1. Tuning forks

4.1. A wave that bounces off a surface that it cannot pass through
4.2. The wave is stopped by an object
4.3. EXAMPLES
4.3.1. Mirriors
4.3.2. Wall ball
5. Refraction
5.1. The bending of a wave as it enters at an angle
5.2. Wave enters a medium at a different speed
5.3. EXAMPLES
5.3.1. Pen in the water
5.3.2. Lawn mower changing from grass to gravel
