1True or False: when two waves combine, they do not exhibit superposition.
False
2States that when two or more waves cross at a point, the displacement at that point is equal to the sum of the displacement of the individual waves.
The principle of superposition
3Is an important idea that can explain phenomena including interference, diffraction, and standing waves.
superposition
4Within the physical world, the observation of superposition is known as ??
interference
5If the two waves are in phase there is constructive interference:the result amplitude is large, equal to the sun of the two wave amplitudes.
constructive interference
6If the two waves are antiphase, there us destructive interference: the resulting amplitude is small, equal to the difference between the two wave amplitudes.
Destructive Interference
7is equal to the absolute value of the difference in frequency of the two waves.
beat frequency
8is the spreading out of waves as they pass through an aperture or around object.
diffraction
9These are the waves that appear to be vibrating vertically without traveling horizontally.
standing wave
