|
|
The lowest part of a transverse wave. |
Trough |
|
|
A wave that moves the medium parallel to direction in which the wave travels |

|
|
A wave that occurs at the surface between two mediums |
Surface wave |
|
|
The maximum distance the particles of a medium move away from their rest positions as a wave passes through the medium. |

|
|
The distance between two corresponding parts of a wave |

|
|
The number of computer waves that pass a given point in a certain amount of time |
Frequency |
|
|
Unit of measurement for frequency |
Hertz (Hz) |
|
|
The bouncing back of a wave when it hits a surface through which it cannot pass |
Reflection |
|
|
The angle between an incoming wave and an imaginary line drawn perpendicular to the surface of the barrier or new medium. |
Angle of incidence |
|
|
The angle between a reflected wave and an imaginary line drawn perpendicular to the surface of the barrier. |

|
|
The bending of waves as they enter a different medium |

|
|
The interaction between waves that meet. |
Interference |
|
|
The interference that occur s when two waves combine to make a wave with a larger amplitude |
Constructive interference |
|
|
The interference that occurs when two waves combine to make a wave with a smaller amplitude. |
Destructive interference |
|
|
A wave that appears to stand in one place,even though it is really two waves interfering as they pass through each other. |
Standing wave |
|
|
A point of zero amplitude on a standing wave |
Node |
|
|
A point of maximum amplitude on a standing wave. |
Antinode |
|
|
The increase in the amplitude of vibration that occurs when external vibrations match the objects natural frequency. |

Surface wave on the ocean caused by an underwater earthquake. |
Tsunami |
|
|
Instrument used to detect and measure earthquakes. |
