1. Mechanical Waves

2. Waves
A disturbance that transfers energy across a distance.

3. Mechanical Wave Waves that transfer energy through a medium.
A medium is matter; a substance; a solid, liquid, or gas.
A mechanical wave requires a solid, liquid, or gas to transfer energy through.

4. Transverse Wave
A mechanical wave that travels at right angles to the disturbance.
The energy travels perpendicular to the direction that the medium moves.

5. Transverse Wave

6. Transverse Wave Examples are: Water waves Rope waves
Some seismic waves

7. Longitudinal Wave
A mechanical wave that travels in the same direction as the disturbance.
The energy travels parallel to the direction that the medium moves.

8. Longitudinal Wave

9. Longitudinal Wave Examples are: Sound waves Slinky being pushed
Some seismic waves
