| Cornea | Transparent covering on eyeball.
🗑
|
||||
| Focal point | Single point on optical axis of a concave mirror/convex lens where light rays press through.
🗑
|

| Incoherent light | Light that has more than than 1 wavelength and does not travel with its crests and troughs aligned in same direction.
🗑
|
||||
| Index of refraction | Property of a material indicating how much light slows when traveling in a material.

| Total internal reflection | Occurs when light strikes a surface between 2 materials. Completely reflects back into first material.
🗑
|
||||
| Translucent | Material that allows some light to pass through but not enough to see clearly.
🗑

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.
