🗑
|
||||
| Resting position | The position in which the wave would sit if there was no disturbance moving through it
🗑
|
||||
| Mechanical waves | Waves that travel through gases, liquids, or solids
🗑
|
||||
| Medium | Material through which a wave travels
🗑
|
||||

🗑
|
||||
| Refract | To bend waves as they enter a new medium at an angle
🗑
|
||||
| Lens | A curved piece of glass or other transparent material that is used to refract light
🗑
|
||||
| Convex Lens | A lens that is thicker in the center than at the edges
🗑
|
||||
| Concave Lens | A lens that is thinner in the center than at the edges

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.
