In a compression wave, particles in the medium move
nikdorinn [45]

in the same direction as the wave

Explanation:

In a compression wave, the particles in the medium moves in the same direction as the wave source.

A wave is generally defined as a disturbance that transmits energy.

  • There are two types of waves based on the direction through which they are propagated.
  • Transverse waves are directed perpendicularly in the direction of propagation.
  • Examples are electromagnetic waves.
  • Longitudinal waves are parallel to their source. Examples are sound waves, p-waves.
  • They are made up of series of rarefaction and compression.

What's something that I've done in my life that is related to physics
Allisa [31]

That's a very difficult question to answer, because you give us
no information regarding what you have done in your life. 

We can only assume that you have most likely breathed on occasion,
floated on your back in the ocean, lake or pool, maybe fallen off of a
ladder or out of bed, felt the warmth of the sun on your cheek, seen
a rainbow after a rainshower, heard the sound of thunder during a
summer storm, taken a trip in an airplane, and waited for a cup of
hot chocolate to cool off.  The richness of any of these experiences
is greatly enhanced when you understand some of the Physics involved.
