waves

2. is the opposite of a crest, so the minimum or lowest point in a cycle
4. The P waves (Primary waves) in an earthquake are examples of Longitudinal waves
5. wave a wave produced by the acceleration of an electric charge and propagated by the periodic variation of intensities of, usually, perpendicular electric and magnetic fields.
12. on the elastic and inertial properties of that medium.
13. a wave is the time taken for one complete cycle.
14. a radio wave with a wavelength between 100 and 1000 meters (a frequency between 300 kilohertz and 3000 kilohertz)medium wave - a radio wave with a wavelength between 100 and 1000 meters.

1. waves-are both transverse waves and longitudinal waves mixed in one medium.
3. waves do not require a medium to travel (light, radio).
6. Waves In a longitudinal wave the particle displacement is parallel to the direction of wave propagation.
7. the change of direction of a ray of light, sound, heat, or the like, in passing obliquely from one medium into another in which its wave velocity is different.
8. the height of an wave.
9. Waves In a transverse wave the particle displacement is perpendicular to the direction of wave propagation
10. is the point on a wave with the maximum value or upward displacement within a cycle.
11. length-Physics. the distance, measured in the direction of propagation of a wave, between two successive points in the wave that are characterized by the same phase of oscillation.
