Term
|
Definition
| a device that can demonstrate simple harmonic motion when its bob, suspended by a string or light rod, is pulled to one side and released, causing it to swing back and forth. |
|
|
Term
|
Definition
| a special form of periodic motion that occurs when small forces are applied at regular intervals to an oscillating/vibrating object and the amplitude of the vibration increases. |
|
|
Term
|
Definition

|
Term
|
Definition
| a wave whose disturbances occur at a constant rate |
|
|
Term
|
Definition
| A mechanical wave in which the disturbance is parallel to the direction of the wave travel |
|
|
Term
|
Definition

Term
|
Definition
| a wave pulse that strikes a boundary between two mediums |

|
Term
|
Definition
| a returning wave that results from some of the energy of the incident waves' pulse being reflected backward |

Term
| Principle of Superposition |
|
Definition
| the placement of a medium caused by 2 or more waves is the algebraic sum of the displacements of the individual waves |

|
Term
|
Definition
| the point with the largest displacement when two wave pulses meet |
|
|
Term
|
Definition
| a wave that appears to be standing still; caused by the interference of two traveling waves in different directions |
