🗑
|
||||
| medium | the material through which a wave travels
🗑
|

| mechanical wave | a wave that requires a medium through which to travel
🗑
|
||||
| vibration | a repeated back-and-forth or up-and-down motion
🗑
|
||||
| transverse wave | a wave that moves the medium in a direction perpindicular to the direction in which the waves travel
🗑
|
||||
| crest | the highest part of a transverse wave
🗑
|
||||
| trough | the lowest part of a transverse wave
🗑
|
||||
| longitudinal wave | a wave that moves a medium in a direction parallel to the direction in which the waves travel
🗑
|
||||
| compression | the part of a longitudinal wave where the particles of the medium are close together
🗑
|
||||
| rarefaction | the part of a longitudinal wave where the particles of a medium are far apart
🗑
|
||||
| amplitude | the maximum distance the partcles of a medium move away from thier rest position as a wave passes through the medium
🗑
|
||||
| wavelength | the distance between two corresponding parts of a wave
🗑
|
||||
| frequency | the number of complete waves that pass a given point in a certain amount of time
🗑
|
||||
| hertz (Hz) | unit of measurement for frequency
🗑
|
||||

| law of reflection | the rule that the angle of reflection equals the angle of incidence
🗑
|
||||
| refraction | the bending of waves as they enter a new medium at an angle
🗑
|
||||
| diffraction | the bending of waves as they move around a barrier or pass through an opening
🗑
|
||||
| interference | the interaction of waves that meet
🗑
|
||||
| constructive interference | the interference that occurs when waves combine to make a wave with a larger amplitude
🗑
|
||||
| destructive interference | the interference that occurs when two waves combine to make a wave with a smaller amplitude
🗑
|
||||
| standing wave | a wave that appears to stand in one place even though it is really two waves interfering as they pass through each other
🗑
|
||||
| node | a point of zero amplitude on a standing wave
🗑
|
||||
| antinode | a point of maximum amplitude on a standing wave
🗑
|
||||

🗑
|
||||
| P wave | a longitudinal seismic wave
🗑
|
||||
| S wave | a transverse seismic wave
🗑
|
||||
| surface wave | a combination of a longitudinal wave and a transverse wave that travels along the surface of a medium
🗑
|
||||
| tsunami | a huge surface wave on the ocean caused by an underwater earthquake
🗑
|
||||
| seismograph | an instrument used to detect and measure earthquake waves
🗑

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.
