Sound

As air particles are pushed together, they create a region of higher density and pressure in a longitudinal wave.  These areas are called:

• sound waves
• rarefactions
• compressions
• transverse wave

Sound travels at different speeds through different mediums.  Through which medium would your voice travel the fastest?

• Air on a cold winter morning
• Air on a hot summer afternoon
• A metal wall
• A pool
