|---|---|---|---|---|---|
| Wave | a transfer of energy from one point to another via a traveling disturbance
🗑
|
||||
| wavelength | distance from successive crest to crest or trough to trough. It is measure in meters.
🗑
|
||||
| crest | the highest point of a wavelength
🗑
|
||||
| trough | the lowest point of wavelength
🗑
|
||||
| frequency | number of waves passing by per second. It is measured in hertz.
🗑
|
||||
| amplitude | the maximum displacement of the wave. it is the distance from the middle of the wave to the crest
🗑
|
||||
| mechanical waves | waves that are produced by a source of oscillations and required a medium for the energy to move. Some examples are sound waves, water waves and stadium waves.
🗑
|
||||
| electromagnetic waves | waves that are produced by the vibration of charged particles and does require a medium so energy can travel through empty space.
🗑
|
||||
| medium | substance that waves travel through
🗑
|
||||
| transverse waves | waves that travel perpendicular to direction of motion.
🗑
|
||||
| longitudinal waves | waves that travel parallel to the direction of motion. This is done by the compressions and rarefactions in the medium that they are traveling in.
🗑
|
||||
| Reflection | waves bounce off a material and goes in a new direction
🗑
|
||||
| refraction | wave passes through a material and bends. Think contact lens.
🗑
|
||||
| Diffraction | waves bends around or goes through a hole in a material
🗑
|
||||
| Absorption | wave is absorbed by a material and may disappear. An example is sound proofing material
🗑
|
||||
| constructive interference | waves add up and build up a larger wave of higher amplitude
🗑
|
||||
| destructive interference | waves combine and make a wave of smaller amplitude
🗑

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.
