|---|---|---|---|---|---|
| Wave | A disturbance involving the transfer of energy from place to place.
🗑
|
||||
| Energy | In science, it is defined as the ability to do work.
🗑
|
||||
| Medium | The material through which a wave travels.
🗑
|
||||
| Mechanical waves | Waves that require a medium to travel.
🗑
|
||||
| Transverse wave | A wave that vibrates the medium at right angles, or perpendicular, to the direction in which the wave travels.
🗑
|
||||
| Longitudinal wave | A wave that vibrates the medium in the same direction in which the wave travels.
🗑
|
||||
| Compression | An area where the coils are close together.
🗑
|
||||
| Rarefaction | An area where the coils are spread apart.
🗑
|
||||
| Crest | A high point on a transverse wave.
🗑
|
||||
| Trough | A low point on a transverse wave.
🗑
|
||||
| Surface waves | Waves that are a combination of transverse and longitudinal waves. This type of wave travels along a surface that separates two mediums.
🗑
|
||||
| Amplitude | The maximum distance the medium vibrates from the rest position.
🗑
|
||||
| Wavelength | The distance between two corresponding parts of a wave.
🗑
|
||||
| Frequency | The number of waves that pass a given point in a certain amount of time.
🗑
|
||||
| Speed | How far a wave travels in a given amount of time.
🗑
|
||||
| Reflection | An interaction with a surface, in which a wave hits a surface and any part of the wave the cannot pass through the surface bounces back.
🗑
|
||||
| Refraction | The bending of waves due to a change in speed.
🗑
|
||||
| Diffraction | A wave interaction, in which a wave moves around a barrier or through an opening in a barrier, then bends and spreads out.
🗑
|
||||
| Interference | The interaction between waves that meet.
🗑
|
||||
| Constructive interference | Interference in which waves combine to form a wave with a larger amplitude than any individual wave's amplitude.
🗑
|
||||
| Destructive interference | Interference in which two waves combine to form a wave with a smaller amplitude than either original wave had.
🗑
|
||||
| Standing wave | A wave that appears to stand in one place, even though it is two waves interfering as they pass through each other.
🗑
|
||||
| Node | In a standing wave, destructive interference produces points with zero amplitude.
🗑
|
||||
| Antinodes | Points of maximum amplitude on a standing wave are called antinodes.
🗑
|
||||
| Resonance | An increase in the amplitude of a vibration that occurs when external vibrations match an object's natural frequency.
🗑

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.
