destructive interference

400
True
The number of waves generated per second by a source is called the frequency of the source.
500

remains the same

As a pulse travels though a uniform medium, the speed of the pulse ____.

500
longitudinal

frequency
As a wave passes across a boundary into a new medium, which characteristic of the wave would NOT change?
500
False
Doubling the frequency of a wave source (without altering the medium) doubles the speed of the waves.
