Answer 2

Option(c) is NOT an example of a longitudinal wave because it is not producing sound.

Explanation:

• Longitudinal waves are waves in which the vibration of the medium is parallel ("along") to the direction the wave travels and displacement of the medium is in the same (or opposite) direction of the wave propagation.
• Mechanical longitudinal waves are also called compressional or compression waves, because they produce compression and rarefaction when traveling through a medium, and pressure waves, because they produce increases and decreases in pressure.
• A wave along the length of a stretched Slinky toy, where the distance between coils increases and decreases, is a good visualization
