=**17.1 Waves**=

-water is the medium - is created when a source of energy causes a vibration to travel through a medium - classified by the way they move through a medium
 * Mechanical Waves**- is a disturbance in matter that carries energy from one place to another

Transverse Waves Longitudinal Waves Surface Waves
 * Types of Mechanical Waves**

-crest is the highest point in the wave. -trough is the lowest point. Ex) -shaking a rope. - oceans wave.
 * Transverse Waves**- a wave that causes the medium to vibrate at right angles in the direction in which the waves travels.

Rarefaction- and area where the particles in a medium are spread out. Compression- an area where the particles in a medium are spread close together. Examples: - Spring -Slinkies
 * Longitudinal Waves-** a wave in which the vibration of the medium is is parallel to the direction the wave travels.


 * Surface Waves-**A wave that travels along a surface separating two media.
 * Example of Surface Wave**- The well known, and loved ocean waves.
