WAVES

6. - a wave vibrating at right angles to the direction of its propagation.
8. wave - A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium
9. - a periodic disturbance of the particles of a substance that may be propagated without net movement of the particles, such as in the passage of undulating motion, heat, or sound
11. -A compression is a region in a longitudinal wave where the particles are closest together
13. - is the opposite of a crest, so the minimum or lowest point in a cycle
14. - the capacity for doing work.

1. is the point on a wave with the maximum value or upward displacement within a cycle.
2. - the oscillating, reciprocating, or other periodic motion of a rigid or elastic body or medium forced from a position or state of equilibrium.
3. -A substance that makes possible the transfer of energy from one location to another, especially through waves. For example, matter of sufficient density
4. - Rarefaction. A rarefaction is a region in a longitudinal wave where the particles are furthest apart.
5. - the number of crests of a wave that move past a given point in a given unit of time.
7. - distance between corresponding points of two consecutive waves.
10. - the maximum displacement or distance moved by a point on a vibrating body or wave
12. - is a unit of frequency, defined as the number of complete cycles of a periodic signal that take place in one second.
