🗑
|
||||
| Opaque | material that reflects or absorbs all light that strikes it
🗑
|
||||
| Primary colors | Three colors that can be combined to make any other color

🗑
|
||||
| Electromagnetic spectrum | complete range of electromagnetic waves placed in order of increasing frequency
🗑
|
||||
| Primary colors of light | Red, Green, and blue. When all mixed together it creates white light
🗑

🗑
|
||||
| Resting position | is the position in which the wave would sit if there was no disturbance moving through it.
🗑
|
||||
| Electromagnetic waves | transfers electric and magnetic energy
🗑
|
||||

🗑
|
||||
| Law of reflection | the angle of incidence equals the angle of reflection
🗑
|
||||
| Convex lens | Lens that are thicker in the center than 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.
