True or False? Two waves cannot exist in the same space or in the same medium at the same time.
True
False
When a compression interferes with another compression, what occurs?
They counteract and the wave stops.
They combine to create a larger compression.
They combine to create a rarefaction.
None of the above.
When a crest and a trough interfere, what occurs?
They combine to create a higher amplitude wave.
They counteract and the wave either lessens or stops completely.
The wave changes into a longitudinal wave.
If waves overlap and are in phase, how will that affect the resultant wave?
Decrease the amplitude
Increase the amplitude
Decrease the frequency
Increase the frequency
What is the height of a wave from equilibrium?
Amplitude
Interference
Wavelength
Sound

Review: What is it called when a wave bounces off an object?
Reflection

Diffraction
Two wave pulses one with a positive amplitude the other with equal negative amplitude travel on a cord approaching each other. What is the result of the oscillations when the pulses reach the same point?
It is constructive interference with twice the amplitude
It is destructive interference with zero amplitude
It is constructive interference with slightly greater amplitude
It is constructive interference with the negative amplitude
The standing wave is produced
