|---|---|---|---|---|---|
| convex | show 🗑
|
||||
| radiation (from the spectrum) | show 🗑
|
||||
| EM spectrum | show 🗑
|
||||
| show | the color of light with the shortest wavelength (the most energy)
🗑
|
||||
| red | show 🗑
|
||||
| infrared | show 🗑
|
||||
| show | has slightly shorter wavelengths than violet light; this EM wave has frequencies too high therefore it can cause a sunburn
🗑
|
||||
| show | Objects that do not let any light pass through. They reflect or absorb the light, or both.
🗑
|
||||
| translucent | show 🗑
|
||||
| transparent | show 🗑
|
||||
| black | show 🗑
|
||||
| show | All 7 colors reflect and bounce into our eyes.
🗑
|
||||
| absorption | show 🗑
|
||||
| show | Light is sent in many directions as it passes through a medium. Ex: dust or small particles
🗑
|
||||
| show | When light bounces off a surface Ex: mirror
🗑
|
||||
| show | When a wave changes direction as it goes through one type of medium into another Ex: prism
🗑
|
||||
| show | A mirror that is curved inward like a bowl; causes an object to look bigger or magnified
🗑
|
||||
| expand | show 🗑
|
||||
| show | Decrease in the volume (or size) of an object because of a decrease in temperature
🗑
|
||||
| show | the only part of the EM spectrum that we can see
🗑
|
||||
| radio waves | show 🗑
|
||||
| show | the second slowest EM wave; we use it to heat food and in cell phones
🗑
|
||||
| show | an EM wave with a very high frequency; the waves can pass through tissue in your body but is absorbed by bone
🗑
|
||||
| show | the EM wave with the highest frequency of them all; they are used for medical imaging like MRI and CT scans as well as to treat some diseases like cancer
🗑
|
||||
| show | a material that transfers energy well because it traps in air and stays hot. Ex: any kind of metal
🗑
|
||||
| show | a material that does not transfer energy well because it lets air flow through, doesn't stay hot. Ex: glass, wood, ceramic, wool, rubber, brick, plastic
🗑
|
||||
| show | heat is transferred from one object to another when they are touching
🗑
|
||||
| show | heat is transferred from one object to another through a gas or liquid
🗑
|
||||
| Radiation (heat transfer) | show 🗑

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.
