Mechanical Waves
Explanation:Sound waves in air are longitudinal waves because particles of the medium through which the sound is transported vibrate parallel to the direction that the sound wave moves. A vibrating string can create longitudinal waves.
The trombone is a wind musical instrument and as all musical instruments can produce a standing (or stationary) wave.
This kind of waves is the result of the composition of two waves that produces a pattern that looks like it is not moving but just vibrating. Some points of the wave look like they are not even vibrating, they just stand still, and they are called nodes. Other points of the wave vibrate from the maximum positive value to the maximum negative value and are called antinodes.
