---|---|---|---|---|---|
wave | is a destebaence that transfers energy from place to place
🗑
|
||||
energy | as the ability to do work
🗑
|
||||
medium | material at which a wave travels
🗑
|
||||
mechanical wave | waves that require medium through which to travel
🗑
|
||||
vibration | is repeated back-and-fourth or up-and-down
🗑
|
||||
transverse wave | waves that move the medium at right angles to the direction in which the wave travels
🗑
|
||||
longitudinal wave | move the medium parallel to the direction in which the waves traveles
🗑
|
||||
compression | a part where all the coils are close together
🗑
|
||||
rarefaction | these parts were all the coils are spread out
🗑
|
||||
trough | lowest part of a transverse wave
🗑
|
||||
crest | highest part of a transverse wave
🗑
|
||||
wavelength | the distance between two corresponding parts of a wave
🗑
|
||||
amplitude | the maximum distance that the particles of the medium carrying the wave
🗑
|
||||
frequency | the number of waves that passes a certain spot in a certan amount of time
🗑
|
||||
hertrz | frequency is measured in units called ........
🗑
|
||||
speed of wave | speed= wavelength+ frequency
🗑
|
||||
reflection | this interaction with a surface (seeing yourself in water)
🗑
|
||||
refraction | the bending of waves due to a change in speed
🗑
|
||||
diffraction | when two waves going in two different directions meet
🗑
|
||||
constructive interference | the interference that occurs when waves combine to make a wave with a larger amplitude
🗑
|
||||
destructive interference | an interference that occurs when waves combine and get smaller
🗑
|
||||
resonance | is an increase in the amplitude of a vibration
🗑
|
||||
standing wave | is a wave that appears to stand taller or in one place, but its the opposite
🗑

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.
