4  A wave is a rhythmic disturbance that transfers energy.

5 A Mechanical wave is just a disturbance that MOVES THRU a medium. The medium could be ANYTHING.

6 A Mechanical wave examples: sound; water waves; even a “people wave” in a football stadium.

7 Caused by Earthquakes + underground nuclear tests. P and S type waves are called body waves, and are not confined to the surface. Rayleigh waves do most of the shaking during a quake.

8  Waves in different mediums travel at different speeds.

9 All waves are made by something that vibrates.

17 They can travel at speeds of up to 1000 kilometers an hour

19 If the wave is moving as fast or faster than the speed of sound, the sound waves pile up IN FRONT into a shock wave called a sonic boom. Sonic boom
