| A | B |
|---|
| Constructive Interference | When 2 waves combine to form a wave with a larger amplitude |
| Destructive Interference | When 2 waves combine to form a wave with a smaller amplitude |
| Reflection | When a wave bounces off a surface |
| Refraction | When a wave bends as it passes thru a different medium |
| Sound waves | Longitudinal waves that need a medium to travel thru |
| Echo | Reflection of sound waves |
| Pitch | Human perception of a waves fequency |
| Loudness | Human perception of a sound waves amplitude |
| Sound speed | Faster in solids and higher temperatures. Slowest in air & low temps. |
| Doppler effect | Apparent change in frequency when the source of wave is moving. Ex: a car horn |
