🗑
|
||||
| What is the major sound of energy on earth? | EM waves from the sun.
🗑
|
||||
| Electromagnetic waves are produced by | the vibration of an electric field and magnetic field together
🗑
|
||||
| The electromagnetic spectrum is the entire range of | EM waves
🗑
|
||||
| The entire electromagnetic spectrum is divided into regions by | wavelengths
🗑
|
||||
| White light is the entire range of | colors of visible light combined
🗑
|
||||
| Refraction can separate white light into | different colors
🗑
|
||||
| Whether an objects transparent, translucent, or opaque is determinded by | transmit light
🗑
|
||||
| Colors of opaque objects are determined by | the color of light they reflect
🗑
|
||||
| The mixing together of colors of light is called | color addition
🗑
|
||||
| When pigments are mixed the result is called | color subtraction
🗑
|
||||
| What are objects that produce visible light? | Luminous
🗑
|
||||
| When white light is refracted, the amount that the light bends depends on which of the following? | the light's waves
🗑
|
||||
| Which of the following is illuminated object | the moon
🗑
|
||||
| Know what the color addition figure looks light | on page 85
🗑
|
||||
| Know what the color subtraction figure looks like | on page 86
🗑
|
||||
| Objects that are determined by the color of light they reflect are called | opaque
🗑
|
||||
| If you feel an increase in temperature you are | absorbing infrared waves
🗑
|
||||
| What two or more light waves overlap and combine | interference occurs
🗑
|
||||
| Light is most easily transmitted through what type of objects | transparent
🗑
|
||||
| Whay does the sky appear blue? | because blue light is scattered more then any other color
🗑
|
||||
| The moon does not produce light of its own. So where does moonlight come from? | Moonlight is sunlight that is reflected off the moon.
🗑

🗑
|
||||
| What does the law of reflection state? | The angle of incidence is equal to the angle of reflection

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.
