|---|---|---|---|---|---|
| Any disturbance that transmits energy through matter or empty space. | wave
🗑
|
||||
| A substance through which a wave can travel. | medium
🗑
|
||||
| Waves that need a medium. | mechanical
🗑
|
||||
| Visible light, radio and tv signals, microwaves, and X-rays. | electromagnetic
🗑
|
||||
| These waves transfer energy without a medium. | electromagnetic
🗑
|
||||
| This wave is a combination of a transverse wave and a longitudinal wave. | surface wave
🗑
|
||||
| Particles move up and down in this type of wave. | transverse
🗑
|
||||
| Highest point of a transverse wave. | crest
🗑
|
||||
| lowest point between each crest. | trough
🗑
|
||||
| Particles move back and forth along a path in this type of wave. | longitudinal
🗑
|
||||
| Area of crowded particles in a longitudinal wave. | compression.
🗑
|
||||
| Area where the particles are spread apart in a longitudinal wave. | rarefraction
🗑
|
||||
| Waves transfer this. | energy
🗑
|
||||
| The maximum distance that the particles of a medium vibrate from their rest position. | amplitude
🗑
|
||||
| The distance from any point on a wave to an identical point on the next wave. | wavelength
🗑
|
||||
| The number of waves produced in a given amount of time. | frequency
🗑
|
||||
| The speed at which a wave travels. | wave speed
🗑
|
||||
| As frequency increases, the amount of this also increases. | energy
🗑
|
||||
| The bouncing back of a ray of light, sound, or heat when the ray hits a surface that it does no go through. | reflection
🗑
|
||||
| A reflected sound wave. | echo
🗑
|
||||
| The bending of a wave as the wave passes from one medium to another at an angle. | refraction
🗑
|
||||
| The bending of waves around a barrier or through an opening. | diffraction
🗑
|
||||
| The combination of two or more waves that result in a single wave. | interference
🗑
|
||||
| Interference that happens when the crests of one wave overlap the crests of another wave. | constructive
🗑
|
||||
| Interference that happens when the crests of one wave and the troughs of another wave overlap. | destructive
🗑
|
||||
| A pattern of vibration that simulates a wave that is not moving. | standing wave
🗑
|
||||
| Whan a vibrating object causes a second object to vibrate. | resonance
🗑

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.
