200
A sound wave is this type of wave?
What is a longitudinal wave.
200
The pitch of a sound depends on this?
What is frequency.

What is density
500
Sound with frequency lower than 20 hz
What is infrasonic.
500
When destructive interference creates an area where sound can not be heard.
What is a dead spot.
500
Using a sound wave to calculate distances or to find things under water.
