|---|---|---|---|---|---|
| amplitude | the measure of how energy is carried by a wave
🗑
|
||||
| Compression Wave | a kind of wave where the matter in the medium moves back and forth in the same direction that the wave travels; has compressions and rarefactions
🗑
|
||||
| crest | the highest point on a transverse wave
🗑
|
||||
| diffraction | describes the bending of waves around a barrier; can also occur when waves pass through a narrow opening
🗑
|
||||
| frequency | measures how many wave links pass a fixed point each second and is expressed in Hertz (Hz)
🗑
|
||||
| interference | occurs when 2 or more waves overlap and combine to form a new wave, can form a larger wave or a smaller wave
🗑
|
||||
| medium | any material- a solid, a liquid, or gas that a wave transfers energy through
🗑
|
||||
| rarefaction | the least dense region of a compressed wave
🗑
|
||||
| refraction | bending of a wave as it charges speed moving from one medium to another
🗑
|
||||
| standing wave | a type of wave that forms when waves of equal length and amplitude, but traveling in opposite directions continuously interfere
🗑
|
||||
| transverse wave | a type of wave such as a water wave where the matter in the medium move back and forth at a right angle to the direction the wave travels (highest- crest, lowest- trough
🗑
|
||||
| trough | the lowest point of a transverse wave
🗑
|
||||
| wave | a rhythmic disturbance that transfers energy through matter or space; it exists only as long as it has energy to carry
🗑
|
||||
| wave length | the disturbance between one point on a wave, and the nearest point just like it on the following wave, as frequency increases wavelength decreases
🗑
|
||||
| Do wave carry energy with, or without transporting matter? | without
🗑
|
||||
| Do all waves need a medium to travel through? explain | No, light waves
🗑
|
||||
| What direction do compressional, and transverse wave move in? | back and forth; up and down
🗑
|
||||
| What regions of a compressional wave is less dense, and what is more dense? | less- compressions
more- rarefactions
🗑
|
||||
| Which travel faster, sound or light waves? | light waves
🗑
|
||||
| what is frequency expressed in? | hertz (Hz)
🗑
|
||||
| The more energy a wave carries the ______ its amplitude | greater
🗑
|
||||
| The less dense the rarefactions the _________ the amplitude is | greater
🗑
|
||||
| (For test know how to count wavelengths) | ⇜
🗑

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.
