Waves are defined as rhythmic disturbances that carry energy without carrying matter. As a
wave travels, the energy moves from one point to another. The matter through which the
wave travels, known as a medium, vibrates but does not drastically change position.
Imagine a stadium full of people doing (you guessed it!) the wave. Each person stands up as
the wave passes, but they don't leave their area. This is also how sound waves pass through
materials. Each particle vibrates as the energy of the wave passes through it, but it eventually
returns to its resting point.
Waves that require a medium to travel are known as mechanical waves. Light is not a
mechanical wave because it can travel through empty space. Sound, on the other hand, is a
mechanical wave because it cannot exist without a material to travel through. Usually,
sound's medium is air. As the energy of sound passes through the air, the molecules it
passes through are disturbed and vibrate left and right.
Mechanical sometimes create disturbances that cause particles to vibrate up and down.
These are known as a transverse waves. Other times, the particles that are disturbed
vibrate left and right, creating a compression or longitudinal wave. Sound is a
compression wave.
longitudinal wave
transverse wave
To better illustrate the differences between these two waves, imagine a slinky stretched out
between two students. If one student wiggles the slinky up and down, a transverse wave is
created. On the other hand, if one student pushes the slinky in the same direction that it is
stretched, a wave of compressed springs will travel along the slinky until it reaches the other
side. This is the way that a sound wave behaves.
Sound is created when air particles are compressed by a speaker, vocal cord, or any other
vibrating object. The air particles closest to the disturbance will move slightly in the direction
away from the vibrating material before returning to their original location. When the particles
are displaced, they press up against more air particles, which will vibrate away in response as
well. This creates a domino effect in which the vibrating energy travels outward from the
source, just like the compressed slinky in the example above.
