|---|---|---|---|---|---|
| Wave | A disturbance that moves through matter or space, carries energy from one place to another.
🗑
|
||||
| Transverse Wave | Causes particles in matter to move back and forth at right angles to the direction in which the wave travels, high points in the wave are called crests and low points are called troughs.
🗑
|
||||
| Compressional Wave | Causes particles in matter to move back and forth along the same direction in which the wave travels.
🗑
|
||||
| Wavelength | The distance between one point on a wave and the nearest point moving with the same speed and direction.
🗑
|
||||
| Frequency | The number of wavelengths that pass by a point each second.
🗑
|
||||
| Law of reflection | The angle that the incoming wave makes with the normal equals the angle that the outgoing wave makes with the normal.
🗑
|
||||
| Refraction | Is the change in direction of a wave when it changes speed as it travels from one material to another.
🗑
|
||||
| Diffraction | Waves can change direction, which is the bending of waves around an object.
🗑
|
||||
| Opaque | Allowing no light to pass through.
🗑
|
||||
| Translucent | Allowing some light to pass through.
🗑
|
||||
| Transparent | Allowing all light to pass through.
🗑
|
||||
| Reflect | Hits a surface and then bounces back.
🗑
|
||||
| Absorb | Take in or soak up.
🗑
|
||||
| Transmit | When light hits an object, the light reflects.
🗑
|
||||
| Loudness | The sound level, or how well a sound can be heard.
🗑
|
||||
| Pitch | How high or low a sound is, determined by the frequency of the vibration.
🗑
|
||||
| Echo Location | The location of objects by reflected sound, in particular that used by animals such as dolphins and bats.
🗑
|
||||
| Echo | A reflection of sound.
🗑
|
||||
| Doppler Effect | The change in frequency of a wave as its source moves in relation to an observer.
🗑

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.
