| A disturbance that transfers energy from one place to a place is called a | wave
🗑
|
||||
| Mechanical waves are created when a source of energy causes a medium to | move
🗑
|
||||
| When an incoming wave combines with a reflected wave in such a way that the combined wave appears to be standing still, the result is a.... | standing wave
🗑
|
||||
| What occurs when vibrations traveling through an object match the objects natural frequency | residence
🗑
|
||||
| A wave travels through a medium because | energy is passed from particle to particle
🗑
|
||||
| Mechanical waves are classified according to | how they move
🗑
|
||||
| Why do you see lightning from a distant storm before you hear thunder | light is faster than sound
🗑
|
||||
| Compressions and rarefactions are characteristic of what type of wave? | longitudinal
🗑
|
||||
| The interaction between two waves that meet is called | interference
🗑
|
||||
| Waves combine to make a wave with larger amplitude in a process called | constructive
🗑
|
||||
| The bending of waves around the edge of a barrier is known as | differaction
🗑
|
||||
| The bending of waves due to a change in speed is called | refraction
🗑
|
||||
| Frequency is measured in | hz (Hertz)
🗑
|
||||
| Wavelength is measured in | m (meters)
🗑
|
||||
| Frequency equals: | speed/wavelength
🗑
|
||||
| Wavelength equals: | speed/frequency
🗑
|
||||
| Speed equals: | wavelength times frequency
🗑
|
||||
| The speed of a wave is its wavelength multiplied by its | frequency
🗑
|
||||
| When a wave hits a surface through which it cannot pass and bounces back , it undergoes | reflection
🗑
|
||||
| The distance between two consecutive crests of a wave is called the | wavelength
🗑

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.
