waves

3. Wave refraction is the bending of waves as it passes from one medium to another.
4. The wavelength of a wave describes how long the wave is.
6. communication refers to the transmission of information or signals through various mediums.
9. A compression is a region in a longitudinal wave where the particles are closest together.
11. transverse wave, motion in which all points on a wave oscillate along paths at right angles to the direction of the wave's advance.
12. The frequency of a wave is the number of waves that pass a point in a certain period of time.
14. interference, in physics, the net effect of the combination of two or more wave trains moving on intersecting or coincident paths.
15. The material through which a wave travels is called a medium.
16. In physics, absorption refers to the reception of energy and describes the process of the energy of a wave being transferred to the matter in which it travels through.
17. Electromagnetic waves are a form of radiation that travel though the universe.

1. Amplitude is a measurement of the amount of energy transferred by a wave.
2. A mechanical wave is a vibration in matter that transfers energy through a material.
5. A longitudinal wave is a type of wave in which the medium's vibration is parallel to the direction of the wave, and the medium's displacement is in the same direction as that of the wave movement.
7. The highest surface part of a wave is called the crest, and the lowest part is the trough.
8. Wave speed is the distance the wave travels in a given amount of time, such as the number of meters it travels per second.
10. reflection, abrupt change in the direction of propagation of a wave that strikes the boundary between different mediums.
13. Energy define as the ability to do work.
