|---|---|---|---|---|---|
| What is a wave? | Rythmic didturbances that carry energy without carrying matter.
🗑
|
||||
| What is a mechanical wave? | Types of waves that require matter to transfer energy.
🗑
|
||||
| What happens in a transverse wave? | The wave energy causes the matter in the medium to move up and down or back and forth at right angles to the direction the wave travels.
🗑
|
||||
| What happens in a compressional wave? | Matter in the medium moves forward and backward along the same direction that the waves travel.
🗑
|
||||
| What is an electromagnetic wave? | Waves that can travel through space where there is no matter.
🗑
|
||||
| What is the amplitude of a transverse wave? | One- half the distance between the crestand the trough.
🗑
|
||||
| When is the amplitude of a compressional wave greater? | Rythmic didturbances that carry energy without carrying matter.
🗑
|
||||
| What is a mechanical wave? | It is the distance between the top of two crests or the distance between the bottom of 2 troughs.
🗑
|
||||
| What is the wavelegnth of a compressional wave? | The distance between the center of a compression to the next, or the distance between the center of a refraction to the next.
🗑
|
||||
| What happens in a compressional wave? | The number of wavelegnths that pass a given point in 1 s.
🗑
|
||||
| What is Reflection? | It is when a wave strikes a surface and bounces off.
🗑
|
||||
| What is Refraction? | The bending of a wave as it moves from one medium to another.
🗑
|
||||
| What is Diffraction? | The bending of waves around a barrier.
🗑
|
||||
| What is interference? | The ability of two waves to combine and form a new wave when they overlap.
🗑

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.
