Question
Answer
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.
