|---|---|---|---|---|---|
| wave | rythmic disturbance that carries energy through matter or space
🗑
|
||||
| medium | a material through which a wave transfers energy
🗑
|
||||
| wavelength | the distance between a point on one wave and the identical point on the next wave
🗑
|
||||
| amplitude | the distance from the crest point to the rest point in a wave
🗑
|
||||
| frequency | the number of compressions that pass through a given point in a second
🗑
|
||||
| frequency is measured in this unit | hertz
🗑
|
||||
| transverse waves | waves that move at right angles to the medium
🗑
|
||||
| compressional wave | when the matter vibrates in the same direction as the medium
🗑
|
||||
| compressional wave consits of two main areas | compression and rarefaction
🗑
|
||||
| four components of a wave | wavelengths, frequencies, amplitudes, velocities
🗑
|
||||
| frequencies above 20,000 hertz | ultrasonic
🗑
|
||||
| frequencies below 20 hertz | infrasonic
🗑
|
||||
| loudness | the human perception of sound intensity
🗑
|
||||
| noise | no set pattern or definite pitch
🗑
|
||||
| resonance | when sound reaches an object at the same frequency as the object's natural frequency, the object will the begin to vibrate
🗑
|
||||
| quality | describes the differences among sounds of the same pitch and loudness
🗑
|
||||
| interference | ability of two or more waves to combine and form a new wave
🗑
|
||||
| constuctive interference | compressions of different waves which arrive at the same place at the same time
🗑
|
||||
| destructive interference | compressions of one wave which arrives with a rarefaction of another wave
🗑
|
||||
| reverbation | the effect produced by many reflections of sound
🗑
|
||||
| acoustics | the study of sound
🗑
|
||||
| natural frequency | when waves reflect back and forth between ends
🗑
|
||||
| crest | highest point of a wave
🗑
|
||||
| trough | lowest point of a wave
🗑

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.
