|---|---|---|---|---|---|
| The maximum displacement from the rest position of a system experiencing periodic motion; half the distance between the extreme positions of the system. | amplitude
🗑
|
||||
| Reducing the amplitude of periodic motion through friction or other resistance. | damping
🗑
|
||||
| The bending of waves around the edges of objects or after passing through openings or gratings. | diffraction
🗑
|
||||
| The perceived difference in received frequency compared to the frequency of a wave source due to the relative motion of the observer and the source. | Doppler effect
🗑
|
||||
| The number of oscillations or other periodic changes completed per unit of time, measured in hertz (Hz) or cycles per second (s–1) in the SI. | frequency
🗑
|
||||
| The interaction of two or more intersecting waves, resulting in a net waveform with amplitudes and periods different from those of the interacting waves. | interference
🗑
|
||||
| A wave in which the oscillations are parallel to the direction of wave travel. | longitudinal wave
🗑
|
||||
| A mass attached to the end of an arm suspended from a pivot point that is free to swing back and forth under the influence of gravity. | pendulum
🗑
|
||||
| The time interval required to complete one cycle of an oscillating system, measured in seconds (s) in the SI. | period
🗑
|
||||
| Recurring back-and-forth or cyclical motion of a system in a regular time interval, called a period. | periodic motion
🗑
|
||||
| Phenomenon of a wave bouncing off a surface. | reflection
🗑
|
||||
| Phenomenon that occurs when a wave’s speed changes as the wave moves through a boundary between different media. If its angle of incidence is other than 90°, the wave bends from its initial path. | refraction
🗑
|
||||
| The condition of an oscillating system when its amplitude increases due to reinforcement by energy added at its natural frequency; the transfer of energy from one vibrating object to another with the same natural frequency. | resonance
🗑
|
||||
| A wave in which the oscillations are at right angles to the direction of wave travel. | transverse wave
🗑
|
||||
| An oscillation in matter or mutually interacting electromagnetic fields that transfers energy from one place to another. | wave
🗑
|
||||
| The distance between corresponding points on adjacent waveforms, such as crest-to-crest or trough-to-trough. | wavelength
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
