A wave that causes the particles of the medium to vibrate parallel to the direction the wave travels
Yes, it is a compressional wave.
Anna, Jessica, Mark -- or Whoever -- you're more likely to receive help if you give us some idea of your thinking about these questions.
ms.sue would it be compressional i am not really sure could you please tell me if i am right thank you
The type of wave you are describing is called a "longitudinal wave." In a longitudinal wave, the particles of the medium (such as air, water, or a solid material) vibrate back and forth in the same direction as the wave is traveling.
To understand how this works, imagine a slinky toy stretched out horizontally. If you push one end of the slinky towards the other end and then release it, a compression (or high-pressure region) will travel through the slinky. As the compression moves, the coils of the slinky move back and forth parallel to the direction of the wave.
You can also think of sound waves as an example of longitudinal waves. When you speak, your vocal cords vibrate, creating compressions and rarefactions in the surrounding air molecules. These compressions and rarefactions then propagate as a sound wave, with the air particles vibrating parallel to the direction of the wave as it travels to your ears.
So, in summary, a longitudinal wave is a type of wave where the particles of the medium move back and forth in the same direction as the wave is propagating.
