| Question | Answer |
| 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 |
