|---|---|---|---|---|---|
| wave | a disturbance that transmits energy through matter or space
🗑
|
||||
| medium | the matter through which a wave travels that determines the speed of a wave
🗑
|
||||
| crest | the highest point of a transverse wave
🗑
|
||||
| trough | the lowest point of a transverse wave
🗑
|
||||
| amplitude | the greatest distance that a particles in a medium move from their normal position when a wave passes; half the vertical distance between the crest and the trough of a wave
🗑
|
||||
| wavelength | the distance between any to successive identical parts of a wave
🗑
|
||||
| period | the time required for one full wavelength to pass a certain point
🗑
|
||||
| frequency | the number of vibrations (crests) that occur in a one second time interval. Measured in Hertz (Hz)
🗑
|
||||
| wave speed | the speed at which a wave passes through a medium
Equation: frequency X wavelength
🗑
|
||||
| doppler effect | an observed change in the frequency of a wave when the source or observer is moving
🗑
|
||||
| reflection | the bouncing back of a wave as it meets a surface or boundary
🗑
|
||||
| diffraction | the bending of a wave as it passes an edge or an opening
🗑
|
||||
| interference | the combination of two or more waves that exist in the same place at the same time
🗑
|
||||
| refraction | the bending of waves due to speed change as they pass from one medium to another
🗑
|
||||
| constructive | any interference in which waves combine so that the resulting wave is bigger than the original wave
🗑
|
||||
| destructive | any interference in which waves combine so that the resulting wave is smaller than the original wave
🗑
|
||||
| standing wave | a wave form caused by interference that appears not to move along the medium
🗑
|
||||
| node | region of no vibration caused by destructive interference
🗑
|
||||
| anti-node | region of maximum vibration caused by constructive interference
🗑
|
||||
| mechanical wave | wave that requires a medium through which to travel ex: sound wave
🗑
|
||||
| electromagnetic wave | a light wave caused by a disturbance in electric and magnetic fields and does not required a medium
🗑
|
||||
| transverse wave | a wave that causes the particles of the medium to vibrate perpendicularly to the direction the wave travels
🗑
|
||||
| longitudinal wave | a wave that causes the particles of the medium to vibrate parallel to the direction the wave travels
🗑

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.
