Solution Steps

Step 1: Understanding the Nature of Sound Waves

Sound waves are mechanical waves that require a medium (such as air, water, or solids) to travel through. They are created by vibrating objects and propagate through the medium by causing the particles of the medium to vibrate.

Step 2: Identifying the Type of Wave

There are different types of waves, including surface waves, electromagnetic waves, transverse waves, and longitudinal waves. Sound waves specifically cause the particles of the medium to oscillate parallel to the direction of wave propagation.

Step 3: Determining the Correct Type

Given that sound waves cause particles to move back and forth in the same direction as the wave travels, they are classified as longitudinal waves. This is in contrast to transverse waves, where particle movement is perpendicular to wave direction.

Final Answer

The answer is \(\boxed{\text{D. Longitudinal}}\).
